THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.


KRISTIE LU STOUT, HOST: I'm Kristie Lu Stout in Hong Kong. And welcome to News Stream where news and technology meet.

Now the surviving suspect in the Boston Marathon bombings is questioned by authorities. And a source says he told them his older brother, not any international terror group, masterminded the deadly attack.

Stopping terror on the tracks. Canadian authorities foil what they say was an al Qaeda linked plot to target a passenger train.

And embassy under attack. We'll go live to Libya's capital after a car bomb blew the front wall off the French diplomatic headquarters there.

Now claims from the surviving suspect in the Boston Marathon bombings appear to suggest that the brothers may have acted alone. Now according to a U.S. government source, Dzokhar Tsarnaev has told investigators that his older brother masterminded the deadly attack. And the motivation was to defend Islam. Now authorities say that those claims must still be verified.

Meanwhile, business owners and residents will be able to return to the blast area for the first time since the bombings in just a few hours. Miguel Marquez has more on both the investigation and the city's recovery.

(BEGIN VIDEOTAPE)

MIGUEL MARQUEZ, CNN CORRESPONDENT: Dzokhar Tsarnaev in his hospital bed charged with a use of a weapon of mass destruction, he was read his rights, has a lawyer and will be tried as any other citizen, not as an enemy combatant.

JAY CARNEY, WHITE HOUSE PRESS SECRETARY: We have a long history here of successfully prosecuting terrorists and bringing them to justice. And the president fully believes that that process will work in this case.

MARQUEZ: Despite his injuries, including a bullet wound to the neck, sedated on a ventilator and restrained, Tsarnaev can still nod his head.

The judge ruling he was alert and able to respond to the charges when asked if he could afford a lawyer, Dzhokhar whispered no.

In the criminal complaint, investigators built a minute by minute account of the Tsarnaev brothers as they moved through the crowds of the marathon. At one point Dzhokhar had his phone to his ear, maybe a ruse. Seconds later, the first bomb.

Only then does he begin to walk away from the bag he's left amid the crowd. 10 seconds later, the second bomb is detonated.

We are also learning about his older brother, Tamerlan Tsarnaev. In 2009, he was arrested for domestic assault after his girlfriend said he beat her up. Last year, he openly argued with a preacher at a mosque he sometimes attended, telling him that holiday celebrations were not allowed by Islam. Again, last January, he disrupted a sermon about Martin Luther King, calling the civil rights leader a nonbeliever.

The revelations and charges just as this city is struggling to recover, a moment of silence marking one week since the attack from the Oval Office and around the country, a solemn tribute.

This is outside Faneuil Hall here in Boston, particular bustling (ph) area. Almost every spot in the city is silent and still.

Another step toward normal, Boylston Street turned over by federal investigators to the city of Boston.

In a sign of the investigation's intensity, a tree, possibly touched by Dzhokhar, removed, taken as evidence. And photos of Dzhokhar withdrawing money from an ATM after a car jacking in the murder of MIT police officer Sean Collier.

This, as the victims continue to heal. 50 in the hospital, two still critical. For some, seriously injured, hope.

Nearly all of the patients that have lost legs are already walking the halls with physical therapists.

Still, grim reminders here just about everywhere. In Medford, the funeral for 29-year-old Krystle Campbell. The church overflowing. The grief unbearable.

(END VIDEOTAPE)

LU STOUT: And that was Miguel Marquez reporting there.

Now another victim was also honored on Monday. Boston University held a memorial for graduate student Lingzu Lu. Her family, you see here, they flew in from China to attend. The service included several musical tributes. And then Lu's father delivered the Eulogy, remembering her as a determined and confident young woman who loved to play the piano and make her family laugh.

And MIT is honoring fallen campus police officer Sean Collier. Vice President Joe Biden will attend his memorial service on Wednesday. And Collierwas killed during last week's manhunt for the marathon bombing suspects.

And that manhunt ended at this home in Watertown, Massachusetts. Now Dzhokhar Tsarnaev hid in this boat. And the SWAT team that captured him spoke to Anderson Cooper about how those final minutes played out.

(BEGIN VIDEOTAPE)

ANDERSON COOPER, CNN ANCHOR: Tell me about Friday night. When was the first indication you got that the suspect had been found?

OFFICER JEFF CAMPBELL, MBTA TRANSIT POLICE SWAT: We gathered up the men that we had left at that point and we started rolling to that location to help in any way that we could. We got out there and several agencies out there, already the suspect was cornered and had been hiding in this boat.

Different agencies that were on scene were trying less lethal means to get the subject to turn himself in. I believe they tried numerous flash- bang grenades. They tried some -- they tried to gas him out of the boat. Just wasn't working.

COOPER: Did you know at the time whether the suspect was conscious or not?

CAMPBELL: We were getting reports from I believe it was the state police helicopter, stated reports from them there was movement inside the boat. They were using the infrared to look through the canopy, the tarp that was on it.

COOPER: They have released those images. We have seen the infrared images. They could tell -- because there were reports that sometimes he was moving, then sometimes he wasn't moving.

CAMPBELL: Correct

OFFICER SARO THOMPSON, MBTA TRANSIT POLICE SWAT: He was going in and out of consciousness because he was losing a lot of blood.

CAMPBELL: Which is how the homeowner actually found him was from a blood trail leading up to the boat, he saw a slice in the canopy so he took a peek inside. That's when he saw the suspect inside the boat and made his 911 call.

COOPER: But at that point did you know if he was armed, if he had explosives on him?

THOMPSON: He had gone into a fire fight earlier that day with some of the officers who responded to that scene after the 911 call, some of our patrol officers. And we know for sure there was a weapon there.

CAMPBELL: You have to assume with the events of the last week that there were explosives as well.

COOPER: So you guys get together to come up with a plan. What was the plan? What was the idea?

CAMPBELL: It was basically just to get across that danger zone. There was an open area from where the house was that was our final line of cover if he stops firing at us. We have no protection getting across that danger zone. So we had a Kevlar shield up in front of us and we all lined up in a stack behind that shield to cross that danger zone.

COOPER: Were you thinking you're going to have to go into the boat to come out or was your understanding he was going to come out?

CAMPBELL: It was our understanding he was giving himself up. He was sitting on the edge of the boat with one leg hanging over the side.

COOPER: When you first saw him, what did you think?

CAMPBELL: This is the target, this is the job, you know. We're almost done with this and let's do it. Let's just do what we're trained to do. This is the suspect. We're trained to go in and apprehend him.

You could see one hand was clear of any weapons, but each time he went back the other way, his hand went down inside the boat out of our view. And I know everybody here, we've spoken about it, each time he did that, we had to assume that he was reaching for either a weapon, a firearm, or some type of explosive ignition device to try to draw us in and then take us out in a suicide type manner.

He did that a couple of times, as we were still approaching towards him. We got close enough that at one point, where both of his hands were up, because of the rocking back and forth, both of his hands were up, we could see that there were no weapons in them, no ignition devices, we broke away from the shield protective cover and we just rushed him.

We put hands on him, grabbed him and pulled him off the boat. Down on to the ground. At that point, it just became I don't want to say typical, but an arrest situation. You check the suspect for weapons. Of course him, we had to check him for explosives, take his sweatshirt off because he may have been wearing a suicide vest.

At that point, we still didn't know if the boat had been rigged with explosives, some type of timed device or anything like that just because of their behavior all week long. So at that point we needed to get him away from the boat.

As soon as he was checked for anything, handcuffed, we picked him up and ran like hell to get away from that boat. And got him over to where the medics are and the federal agents, who were taking him into custody.

COOPER: What goes through your mind? You were focused for a week on finding this guy. You've seen horrible things on that Monday, you know, you've been working around the clock. To know that he's finally apprehended, what does it feel like?

SGT. DET. SEAN D. REYNOLDS: It's a relief, but we're not sure it's over yet. We're still on that mode. We've still been working, we haven't had a chance to really sit down, watch the news and think about it and see what's actually going on. So we're still in that heightened state as I'm sure everybody is, and maybe in a couple weeks we'll get a chance to sit down and reflect on what actually happened.

(END VIDEOTAPE)

LU STOUT: Wow, some riveting detail there from the SWAT team that captured Dzhokhar Tsarnaev. And later in the show, we'll take you live to the Russian Republic of Dagestan and that is where the suspect's mother lives. In fact, our Nick Paton Walsh spoke to her just a short time ago.

Now, a U.S. government source says that Tsarnaev brothers can probably be classified as self-radicalized jihadists, that's based on the preliminary bedside interviews with Dzhokhar. It's believed that the internet played a role.

Now the older brother Tamerlan allegedly had a link to this jihadist's video on his YouTube account. And officials say such extremist videos may have helped shape his views. But investigators still do not know if the brothers received help planning and carrying out the attack.

Now former CIA officer Bob Baer tells Anderson Cooper that the internet could not have taught them everything.

(BEGIN VIDEO CLIP)

BOB BAER, FORMER CIA OFFICER: You know, on these fuses on the grenades, improvised grenades, I mean, how do you light them under pursuit? I mean, you'd have to know to use the car lighter. You'd have to know how long the fuse was. I've spent the last week talking to people who build these things for a living. And every one of them has said no you cannot pick this stuff up on the internet and make it all work. Yes, a lot of it is there, but not to this degree. I just don't believe it. You know, this is speculation at this point. They may have gotten lucky, but I don't think so.

(END VIDEO CLIP)

LU STOUT: And still, the simplicity of the bombs is one of the most frightening aspects of the attack. And CNN commissioned an explosives expert to build a pressure cooker bomb to find out how they work and to prevent them from doing so much damage.

David Mattingly shares what he learned.

(BEGIN VIDEOTAPE)

DAVID MATTINGLY, CNN CORRESPONDENT: At this remote desert testing ground, experts from New Mexico Tech replicate and explode bombs used by terrorists. On this day, there's a sense of urgency.

After Boston, what are you worried about? Could this be the future of domestic terrorism?

VAN ROMERO, NEW MEXICO TECH: Well, you're always worried about copy cats. You know, are more and more people are going to be using this?

MATTINGLY: This is a pressure cooker bomb similar to the bombs in Boston. And we're about to set it off.

UNIDENTIFIED MALE: All right. Are we going to do the countdown?

MATTINGLY: In the wrong hands, we already know how deadly this bomb can be. And we're not taking any chances.

For safety reasons, we've had to retreat to this mountain top here. We are now over a quarter of a mile away from where we left that pressure cooker.

But that's still not far enough to avoid flying shrapnel, so we're watching from inside a bunker.

UNIDENTIFIED MALE: Five, four, three, two, one.

(SOUND OF EXPLOSION)

MATTINGLY: Wow, that white smoke looks just like what we saw in Boston.

ROMERO: Yep.

MATTINGLY: I could feel it all the way up here.

ROMERO: Oh yeah, that shockwave will travel all the way.

MATTINGLY: But down below is the real shock.

ROMERO: At this point, we're looking for fragments.

MATTINGLY: One bomb turned into thousands of weapons scattered more than 100 yards. This was part of the pressure cooker, now mangled and razor sharp.

No wonder so many people got hurt.

Instead of nails, we filled the pot with nuts from a hardware store. Shot out like bullets, they pierced plywood, some even melted from the heat.

Look at the back of it?

How fast were these things moving when they went out of there?

ROMERO: They can travel 1,000, 2,000 feet a second.

MATTINGLY: A second, that's faster than sound.

ROMERO: Right. They'll move faster than the speed of sound. These things will actually get in front of the shockwave and hit you before the shock -- the pressure wave does.

MATTINGLY: You're hit before you even hear it.

ROMERO: That's right.

MATTINGLY: Here what the blast looks like using a high speed camera.

And intense ball of fire less than 20 feet across. But watch the white rings on the desert floor, that's the shockwave. Engineers studying this blast say there's a lesson in here for first responders.

Let's say I'm a first responder, what do I need to be aware of when I come up on a scene like this?

ROMERO: Well, there's a lot of shrapnel around. It's very hot. It's very sharp. You can easily cut yourself. There could be unexploded ordinance, parts of the bomb that are still left over that didn't explode when it was supposed to explode. That could go off at any time.

MATTINGLY: But for potential bystanders, out of this demonstration there are only words of caution. By the time you hear the boom, you could already be hit. Awareness of your surroundings could be the only defense.

David Mattingly, CNN, Secorro, New Mexico.

(END VIDEOTAPE)

LU STOUT: Wow. Incredible and frightening detail about how those bombs work. You're watching News Stream. And coming up next, France's ambassador to Libya tells officials he will not leave the country despite a car bomb attack at the French embassy in Tripoli. Coming up, we'll get the latest on the investigation.

And disaster averted, Canadian police arrest two men they say were plotting a terror attack on board a passenger train.

And tensions rise between Japan and China after Beijing sends government ships to waters near a chain of islands claimed by both.

(COMMERCIAL BREAK)

LU STOUT: Now a criminal investigation is underway to determine who is behind a car bombing at the French embassy in Libya. The explosion was so powerful, it ripped the front wall off the embassy building and injured two French security guards and a 13-year-old girl who is in a nearby house. Libya's deputy prime minister says he has spoken to the French ambassador to Tripoli and the ambassador has made it clear he will not leave Libya.

Let's get the very latest on this. Jomana Karadsheh is in Tripoli, she joins us now live on the phone. Jomana, this is a major attack on an embassy in the capital. What more have you learned about the aftermath?

JOMANA KARADSHEH, CNN PRODUCER: Kristie, we just left the scene a short while ago, headed to a government press conference to hear the latest from the Libyan government. This is definitely a very substantial blast, a major bombing that really affected homes in this very residential neighborhood of Tripoli, as we mentioned it did blow the front wall of the embassy, caused severe damage to the embassy and also nearby homes.

We see French investigators who seem to be in the lead in this investigation collecting evidence from the scene of the blast. They're working alongside the Libyan criminal investigation. They have sealed off the feel of the bombing and we're collecting evidence we were there. People in the neighborhood told us that the blast happened just after 7:00 this morning, a massive blast that woke up people blocks away from the French embassy.

Of course, people in the area, Kristie, (inaudible) on the lax security here in Libya and the lack of accountability by the government here after many attacks on embassies. But as you mentioned, this is the first major attack that we have seen take place in the capital Tripoli targeting western interests.

LU STOUT: Yeah, someone is exploiting this lack of security, but who? Who is responsible for this attack?

KARADSHEH: Well, Kristie, a few months ago as you remember when the French intervention, the French military intervention in Mali, there was increased security here in Libya. There were concerns that Islamic extremist groups, some with ties to al Qaeda (inaudible) to the operation in the eastern part of the country, also some of them taking -- using the southern desert region in Libya for training camps and you know logistical bases here that they could strike French interests here in Libya.

We've also (inaudible) speaking to two French embassy staff today saying that they had worries about this a few months ago, but no one expected this to happen right now.

People in the neighborhood we've spoken to also pointing the finger at al Qaeda linked groups. We have seen a lot of activity in the eastern region of the country, Kristie. If you remember, that deadly attack that killed the U.S. ambassador here in Benghazi, Ambassador Chris Stevens and three other Americans. And we've seen a number of different attacks also on foreign diplomatic missions (inaudible) these Islamic extremist groups, but this is the first we've seen here in Tripoli targeting foreign interests. And the deputy prime minister telling us earlier, Kristie, that it's early to come to conclusion as to who is behind this attack.

LU STOUT: All right, understood. Jomana Karadsheh live on the line from Tripoli, thank you.

Now right here next to me this is a visual representation of all the stories we're covering for you this hour on News Stream. And earlier, we heard from the Boston SWAT team that apprehended the marathon bombing suspects Dzhokhar Tsarnaev.

But now, we want to turn our attention to Canada where police say that they have foiled a terror plot. Now two men are in custody accused of planning an attack on a passenger train. We should learn more about the case when the accused appear in court in just under two hours time.

Paula Newton reports from Ottawa.

(BEGIN VIDEOTAPE)

PAULA NEWTON, CNN CORREPSONDENT: Canadian police say after months of surveillance two suspects are now in custody and charged with conspiracy to commit a terrorist act. This plot, they say, allegedly involved trying to derail or bomb trains, that would be the Villa passenger trains here in Canada.

But they also say this had a link to al Qaeda from Iran, something that we have not heard before in connection with terrorist cells. Take a listen.

JAMES MALIZIA, ASST. COMMISSIONER, RCMP FEDERAL POLICING OPERATIONS: The individuals were receiving support from al Qaeda elements located in Iran. Now I can tell you that there is no information to indicate that these attacks were state sponsored.

NEWTON: The suspects will appear in court Tuesday morning. Police say that they believe this was a real threat, but not an imminent threat. They want to be clear that this had no connection to the Boston bombings, but also that at no time was the public in danger. They say this because they allowed many elements of this plot to carry out at the same time wiretapping phones and computers and homes and addresses to be able to listen in and gather more evidence.

They do say that the threat was no imminent at all, but that it was a real threat, a real threat to perhaps even derail or target a train from Canada into the United States.

Paula Newton, CNN, Ottawa.

(END VIDEOTAPE)

LU STOUT: Now Iran is denying Canadian claims that the plot is linked to al Qaeda elements inside Iran. Now its mission to the United Nations issued a statement saying this, quote, "al Qaeda has no possibility to do any activity inside Iran or conduct any operation abroad from Iran's territory. And we reject strongly and categorically any connection to this story."

Now in Spain, police have arrested two men with suspected links to an al Qaeda group, but they add that there was no indication that the men were about to launch any attack. The Spanish interior ministry says one suspect is of Algerian origin, the other man is from Morocco. And these arrests come days ahead of the Madrid Marathon, which takes place on Sunday, but authorities have not linked the events.

Now to France, which could soon become the 14th country in the world to legalize same-sex marriage, that's after a final vote in the national assembly later today. Legislation is expected to pass, though it also gives same-sex couples the right to adopt. But opponents could still refer the matter to France's constitutional council. Now there have been huge protests in recent weeks with conservatives and some religious groups unhappy about the law.

Now still to come right here on News Stream, a reason to celebrate if you're a Manchester United fan. The football club has written another chapter in the record books.

(COMMERCIAL BREAK)

LU STOUT: Broadcasting live from Hong Kong you are back watching News Stream.

Now Manchester United Football Club is used to making history. And yes, this is one for the record books. Let's get more now, Alex Thomas joins us -- Alex.

ALEX THOMAS, CNN SPORTS CORRESPONDENT: Kristie, hi, manager Alex Ferguson is insisting his current side should be regarded as one of the great Manchester United football teams after the club became the first to win England's championship title for a 20th time. Fergie's (ph) men secured the Premier League crown in style at Old Trafford on Monday night. Wayne Rooney and Robin Van Persie combining for one of the goals of the season in a 3-0 thrashing of Aston Villa. Van Persie, signed from Arsenal last year scored a hat trick taking his league tally for the season to 24.

The victory sparked joyous celebrations among United fans. The club has a truly global following. All their supporters delighted to see the side bounce back from the pain in 2012 when they lost the title on the final day of the season on goal difference to local rivals Manchester City.

(BEGIN VIDEO CLIP)

MIKE CUMMINGS, LEAD FOOTBALL WRITER, BLEACHER REPORT: When he first got there he had to knock Liverpool off their perch as he famously said. And then once he got to the top himself he had to keep fighting off contenders. You know, there's Arsenal and there is Chelsea, now Manchester City. He can always bring in -- he can always weave together a team with veterans and also with young players. He fosters young talent and he can also bring in signings like Robin Van Persie. It's one of the key things he's done throughout his career.

(END VIDEO CLIP)

THOMAS: Bayern Munich has made an audacious move in the transfer market as the Champion's League semifinals kick off. They sign one of the world's outstanding young midfielders Mario Gotze from German rivals Borussia Dortmund who play on Wednesday against Real Madrid.

It's sure to be a boost for Bayern ahead of their semifinal first leg later on Tuesday when they play Barcelona. In total, the two clubs have eight titles between them in this championship -- sorry, in this competition. Barca concerned, though, about whether or not world player of the year Lionel Messi will be fit to play. He's got a hamstring problem.

The Chicago Bulls have leveled their NBA playoff series against the Brooklyn Nets, but in the West the Clippers' contest with the Grizzlies isn't as close and that was mainly down to one man, Chris Paul. The outstanding player for Los Angeles -- for the Los Angeles team on Monday night scoring 24 points, racking up nine assists in a 93-91 win, including that spectacular one-handed pull-up buzzer beater after Memphis had threatened to take this one into overtime besides meet again in Memphis on Thursday.

We'll have debate and analysis about Manchester United's record title triumph and Tuesday's Champion's League games, that's all on World Sport in just over three-and-a-half hours' time. For now, Kristie, back to you in Hong Kong.

LU STOUT: All right, Alex Thomas there, thank you.

Still to come right here on News Stream, trying to get insight into the Boston bombing suspects. Friends and family share differing opinions of the Tsarnaev brothers.

And Japan's prime minister warns China to stay off a chain of disputed islands as tensions rise once again in the East China Sea.

(COMMERCIAL BREAK)

LU STOUT: I'm Kristie Lu Stout in Hong Kong. You're watching News Stream. And these are your world headlines.

Now two security guards and a 13 year old girl have been injured after a car bomb exploded in front of the French embassy in Libya. The blast caused extensive damage to the building. Libyan officials says the French ambassador told them he will not leave Tripoli. And the injured girl is being taken to Tunisia for medical treatment.

Now two suspects accused of planning a terror attack on a Canadian passenger train are due in court soon. Authorities say the two men had support from al Qaeda networks in Iran. Tehran is denying that claim.

According to a government source, the surviving suspect in the Boston Marathon bombings has indicated that his older brother Tamerlan was the driving force behind last week's terror attack. And the source says that Dzhokhar Tsarnaev also indicated no foreign terror groups were involved. And he suggested a motivation for bombing the Boston Marathon was to defend Islam.

But the mother of the Boston bombing suspect says her sons did not do it. Now she is currently in the Russian Republic of Dagestan. Our Nick Paton Walsh is there in its capital of Makhachkala.

Nick, you talked to her. What did she tell you?

NICK PATON WALSH, CNN INTERNATIONAL CORRESPONDENT: Highly distraught. I spoke to her in the early hours of this morning, in fact just before midnight, when she didn't believe that Tamerlan was in fact dead suggesting that pictures of a man without any clothes being pushed into a car may, in fact, was him alive. But as the evening went on into the early hours of the morning she did eventually see social media pictures of his dead body and that confirmed in her mind that her oldest son was dead.

What she's not convinced of, though, is that he was involved in the Boston bombings at all, that's something she still holds as an impossibility, considering him to be angelic I think in many ways.

Talking of her younger son Dzhokhar, saying that in fact he doesn't have a voice now. He's still intubated in hospital unable to speak, but that's perhaps part of some process conspiratorial in much of what she said to prevent him from defending himself adequately. Told me that there was a funeral plan for Tamerlan today or tomorrow in Cambridge, Massachusetts at a mosque organized by his sisters and uncle.

Details coming out about her emotions, but also how she really believed that she's in danger, her husband is in danger from the people she believes are behind framing her sons. I think she put a distance between them and the American government. Obviously they went to the U.S. to seek some sort of refuge from the troubles of former Soviet Union, but believes I think at this point that there is somebody out there who is trying to frame her sons.

Deeply, deeply traumatized, did regularly cry during our conversation and absolutely clear in her mind no link to extremism at all. But really struggling to believe anything she's heard from U.S. officials -- Kristie.

LU STOUT: She is distraught. She is in denial. She fears for her own life. She believes that her sons were framed. The mother is still clearly defending her sons, the Boston bombing suspects. Meanwhile the uncle has called them, quote, "losers." So why have we heard these differing accounts from family there in Russia?

PATON WALSH : Well, I believe I think the uncle may have been speaking in the U.S. I think there is a considerable split in the family. The mother and father not really wanting to -- but any (inaudible) at all anything said by the U.S. officials. One of the things I asked her was do you think you'll get a fair trial? And she said only Allah and god will be able to tell that.

I also said, why did this happen to them? Why were they killed? Why did they die in such a way?

And she said, well, it's because their Muslims.

So very, very clear in her mind that there's some other motive behind that potential radicalization we've heard from U.S. officials of her sons, definitely declaring their innocence.

It's clear they want to go to the United States shortly, but it's not clear precisely when that will be. There are investigators -- it wasn't clear if they're Russian or America, and probably Russian, who will be speaking to them at some point today.

So very harrowing time for her indeed, but really portraying a picture of great anger that this has befallen her family. And again total disbelief that her sons could be guilty of the crime they're accused of, Kristie.

LU STOUT: All right, Fascinating details there. Nick Paton Walsh joining us live from Makhachkala, Dagestan. Thank you.

Now family and friends have been a key part of the investigation as the FBI tries to piece together every bit of information it can. But it's been hard to get a view of what the brothers are like, because there are a lot of conflicting opinions.

Nick Paton Walsh, who just gave us their mother's perspective. She believes her sons have been framed for the bombings.

And then there's this view of the younger Tsarnaev from a high school classmate.

(BEGIN VIDEO CLIP)

DEANNA BEAULIEU, FRIEND OF BOMBING SUSPECTS' SISTER: He was just a regular teenager to me. He was quiet, you know, just regular teenager, didn't suspect anything. He was on the wrestling team. He went to parties with, you know, other students. Yeah. He went to the prom. Just regular, pretty much, nothing that caught me off guard that made me suspect anything, which is why I'm really surprised about what happen, because I didn't expect that at all from him.

(END VIDEO CLIP)

LU STOUT: Now the mother again says that the police have got it all wrong. A classmate says that Dzhokhar was just a normal guy. And then there was what their uncle said.

(BEGIN VIDEO CLIP)

RUSLAN TSARNI, BOMBING SUSPECTS' UNCLE: I say what I think what's behind it, being losers, not being able to settle themselves and thereby just hating everyone who did.

(END VIDEO CLIP)

LU STOUT: Another person who could provide invaluable insight is the elder Tsarnaev brother's wife.

Let's bring in Chris Lawrence who is in North Kingstown in Rhode Island where Katherine Russel Tsarnaev have been staying. And Chris, the wife of the slain suspect, what is she saying? What does she know?

CHRIS LAWRENCE, CNN CORRESPONDENT: Well, that's what investigators want to know is they -- Kristie, basically as they try to figure out when and where Tamerlan Tsarnaev assemble -- may have assembled those bombs, they want to find out from Katherine Russel what she may have known about what he was doing and if he had any other affiliations besides his younger brother.

Let me take you to some video we shot just in the last hour or two. It was right here at the hall where Katherine Russel's lawyer arrived. She came out of the house and they left together with federal agents behind them, presumably for another meeting with a lawyer.

We know from him that had -- she has been communicating , but through him with those federal officials. He says she did not know anything about what was going on. He also says that she saw him on Thursday before he -- before she went to work and that she assumed he was home and that he was taking care of their young two-and-a-half year old daughter.

He says that Katherine Russel is devastated by what happened. She feels horrible about what happened to the victims of the Boston Marathon bombing. And she's also dealing with the fact that she has lost not only her husband, but the father of their daughter -- Kristie.

LU STOUT: Tell us more about Katherine Russel as we look at these pictures of her. I mean, who is she. How did she meet and fall in love with Tamerlan Tsarnaev?

LAWRENCE: Basically she grew up in a suburb of Providence, Rhode Islande. She went away to college at Boston and that's where she met Tamerlan maybe about three or four years ago. They got married in 2010. They had a daughter who is now about two-and-a-half. And she went to live with him and his family in that apartment in Cambridge.

Basically, she was raised Christian. She converted to Islam after meeting Tamerlan. And she was described as fairly devout. She wore the hijab, the traditional head scarf. And her lawyer says that she had been working a tremendous amount of hours. He said she worked as a home health care aid and that sometimes she would work, you know, up to six, seven days a week, 70 hours a week and that Tamerlan was the one who stayed home with the young daughter -- Kristie.

LU STOUT: All right. And something else you've learned in the days after the bombing as we look at these pictures of the wife of Tamerlan Tsarnaev there on our screen. It lookedas if the brothers went back to life as usual after the bombings took place, you know, just going back to school, tweeting, using social media. Not on the run at all. What clues have you picked up about their behavior in the days after the bombing?

LAWRENCE: We've spent several days at UMass-Dartmouth talking to friends and acquaintances of Dzhokhar. And they basically were stunned. They saw Dzhokhar this week after the bombing. In fact, we spoke with one student who saw him in the gym the night after the boston marathon bombing. He said all of the students were talking about was the bombing and he talked about it with Dzhokhar. He said something to the effect of, man, can you believe this happened? It's just incredible. And he said Dzhokhar didn't shy away from the conversation that he said something to the effect of, yeah, man, tragedies happen like this, they happen all over the world. It's sad.

So a real insight that Dzhokhar at least went back to walking the dorms. Friends say he went to a pizza party on Wednesday. He swiped his card back into his dorm. So there at least seems to be some effort, at least, to sort of get back to a normal life after what happened on Monday.

LU STOUT: You know, bizarre insight from the classmates there. And we hope to get additional insight from Katherine Russel, the wife of the slain suspect. Chris Lawrence joining us live from Rhode Island, thank you so much for your reporting. Thank you very much for that.

Now let's return to our video rundown now. Earlier, we told you about the criminal investigation underway into a car bombing outside the French embassy in Libya. But now let's return to rising tensions over some remote islands in the East China Sea.

Japan's prime minister is issuing a warning to China. Shinzo Abe says his country will, quote, expel by force any Chinese citizen who lands on the island chain that Japan calls Senkaku. Now China also claims sovereignty over the islands it calls Diaoyu. And earlier, eight Chinese government ships were detected in waters off the disputed islands.

The Japanese coast guard says it is the largest number of Chinese ships in the area since territorial tensions increased last year. And the latest incident comes after Japanese lawmakers visited a controversial war shrine in Tokyo.

Ivan Watson is following all the developments from Beijing. He joins us now live.

And Ivan, you have tension at sea. We have that explicit warning from the Japanese prime minister. How is Beijing responding?

IVAN WATSON, CNN INTERNATIONAL CORRESPONDENT: Well, Beijing has responded by first of all sending the eight coast guard ships to the waters off of these disputed islands early Tuesday morning. The Chinese foreign ministry saying that this was in response to a flotilla of what the Chinese have described as right-wing extremists coming from Japan, dozens of activists who wanted to make a show near the disputed islands and claiming them as Japanese territory. And the Chinese saying that's what prompted them to send an additional five coastguard ships to a total of eight to then patrol off of these waters in an area that China claims for itself as well.

And the maritime faceoff that took place off of these five uninhabited islands, Kristie, on Tuesday then led to a diplomatic spat with the Japanese foreign ministry calling in the Chinese ambassador to Tokyo to formally lodge a protest. The Chinese foreign ministry says that it has also issued a formal protest to the Japanese government over this dispute. And then we have this warning coming from the Japanese prime minister, some quite heated rhetoric. Take a listen.

(BEGIN VIDEO CLIP)

SHINZO ABE, PRIME MINISTER OF JAPAN (through translator): The Senkaku Islands are under our active control. Since it has become the Abe government, we have made sure that if there is an instance where there is an intrusion into our territory, or it seems that there could be landing on the islands, then we will deal with it strongly.

(END VIDEO CLIP)

WATSON: Strongly, as the Japanese prime minister said. And of course Japan and China can't even see eye on how to name these five uninhabited islands. The Japanese calling them the Senkaku Islands, the Chinese calling them the Diaoyu Islands -- Kristie.

LU STOUT: And Ivan, the last few months we've seen new leaders take office in China and Japan, Xi Jinping and Shinzo Abe. How will they manage this ongoing dispute? What's next?

WATSON: Well, the problem is, is over the last six, seven months, the dispute which has lingered for decades has really gotten worse with the Japanese decision in September to effectively nationalize a couple of these islands, officially purchase them from a private owner, and that really irritated the Chinese. We had very angry anti-Japanese protests here in Beijing and in other Chinese cities. And no sign that either country is going to back down with the Chinese insisting that they can continue to patrol with their coastguard ships around the waters of these islands and then the Japanese warnings coming out as well.

Now, both this dispute really taps into some deep seated nationalist sentiments in both countries and bitterness between China and Japan that goes back beyond World War II to the Japanese occupation of China in the 1930s. It also taps into perhaps economic competition with claims that there may be tens of millions of barrels of unfound oil underneath the East China Sea. And then maybe a more existential question, the rise of China as a maritime power and as an economy as well and really challenging increasingly Japan and the economic and maritime spheres. These are all issues that are coming to play here and perhaps suggesting why there is so much anger and rhetoric over what really are pretty much five uninhabited rocks in the East China Sea -- Kristie.

LU STOUT: Yeah, this dispute over those rocks, it's an ongoing, long running dispute and a lot of fear that this could escalate due to events earlier today. Ivan Watson on the story for us live from Beijing, thank you.

Now you're watching News Stream. And coming up next, you will meet this week's leading woman, a musical powerhouse, you know her, you know her by her first name. We'll tell you what drives Beyonce next.

(COMMERCIAL BREAK)

LU STOUT: Welcome back.

Now she is an international singing sensation. And she also has a very keen business sense. Most of the world knows her by just her first name. This week on Leading Women we talk to Beyonce and those who watched her rise to super stardom.

(BEGIN VIDEOTAPE)

LU STOUT: She's one of the top selling, most honored and most influential artists around.

BEYONCE, SINGER: I love art. And I love to sing. I love to perform. It's what I was born to do.

LU STOUT: But when an artist becomes known by only one name, you know she's a star.

NE YO, PERFORMER: Every time you see Beyonce, every time you hear Beyonce, you're expecting to see or hear the best thing you've ever seen or heard, you know from a female artist standpoint.

LU STOUT: But Beyonce is also a business and a brand. From music to film, fashion endorsements and more, how a hair dresser's daughter from Houston, Texas became one of the most powerful and inspirational women in entertainment.

GAIL MITCHELL, SENIOR EDITOR, BILLBOARD MAGAZINE: She had a dream. She envisioned it. Hard work, determination, and this is the result.

LU STOUT: Beyonce Knowles began performing with a girl group at the age of eight. About seven years later, the group by then known as Destiny's Child made its major record label debut. As the breakout star, Beyonce eventually launched a solo career that has firmly established her as an icon.

CORI MURRAY, ENTERTAINMENT EDITOR, ESSENCE MAGAZINE: Beyonce inspires others to dream, because she is always reminding us that she was just this young girl out of Houston, Texas who had a dream to be a performer. And look at her now.

LU STOUT: Where she is now is on the Forbes list of the world's most powerful women with her own fashion line plus multimillion dollar endorsement deals for everything from perfume to Pepsi, her influence spreads beyond her music.

JUNE AMBROSE, FASHION STYLIST: Beyonce's impact on pop culture, you know, not just within the music industry but in the -- I think in terms of the beauty industry I think in terms of fashion, she's becoming really the poster child in terms of her brand being so well rounded.

MURRAY: I mean, this is not a woman who just says she lends her name to it and then she's gone and off to St. Barts or off to her yacht. No, she is there. She's in the meetings. She's doing concepts. Her decisions are really entwined into what her businesses are that have her name, because she knows that it's a reflection of her.

LU STOUT: It's a long way from a girl group in Houston to becoming one of the biggest brands in the business. It's a story of success that inspires others to follow their own dreams.

BEYONCE: I knew that was successful, but not born successful. And I believe with hard work and with a goal and love and positivity then eventually we're going to be fine.

(END VIDEOTAPE)

LU STOUT: And we will have more on Beyonce next week on Leading Women. She'll talk about who inspired her and what she wants to do next. Just log on to CNN.com/leadingwomen for more on the singer and other inspiring women like leading Barrister Cherie Blair.

Now you're watching News Stream. And still to come, there is one accomplishment even Beyonce doesn't have: a billion hits on YouTube. That honor belongs to Psy, of course, and as YouTube marks its eighth birthday, we take a look back and the site's short but illustrious history.

(COMMERCIAL BREAK)

LU STOUT: Rescue workers in southwest China are shifting their focus from finding survivors to relief efforts, that's according to the state run news agency Xinhua. Tens of thousands of people have been left homeless by Saturday's earthquake in Sichuan Province. Some are living in tents, others have no shelter at all.

There is concern that drinking water could run out despite the delivery of supplies, because many of the reservoirs in the area have been damaged.

And the crucial 72 hour window to find survivors after the quake, that closed on Tuesday morning.

Xinhua reports that 23 people are still missing, at least 192 people were killed and 11,000 are injured.

Let's get more now on conditions in the quake zone and across the region. Mari Ramos joins us from the world weather center -- Mari.

MARI RAMOS, CNN WEATHER CORRESPONDENT: Kristie, wow. You know, it's really amazing to think so many people were injured in this. There's still people that are missing.

The concern for the weather in this area is two-fold. First of all, you of course have the possibility of rain which could always complicate things and cause more landslides. And the other thing is the visibility problems. Even if it doesn't rain, when we get those low clouds or even fog in these mountainous areas it could become very difficult indeed.

I want to show you this picture of damage. This is in Chengdu. And it's a little farther away from the epicenter. And you can still see some of the damage here. And there's a couple of things I want you to notice here. First of all, notice these very narrow, winding mountain roads. And here in the background you notice how steep everything is? You see a landslide right there. Some of these -- dozens of these, actually, caused during the earthquake.

Now if you get more rain, you could get more landslides. So that makes travel by road very difficult across these areas.

And notice how steep, almost a vertical drop right over here when you see these mountainsides. That's one concern.

The other thing is the visibility. And you can see how poor visibility gets very, very quickly as you get into some of these mountains, you know, these winding mountain areas, very difficult even for helicopters to fly through here. So that's always going to be a concern for rescue personnel.

This is a picture of one of the many people that were left homeless and you can see they're just trying to cook and live and do what they can in the street.

Temperature wise it hasn't been too much of a concern. Temperatures have been hovering in the 20s, in the lower 20s, maybe the upper teens even in the overnight hours. So that's not a huge concern, but I am concerned about the rain, like I said, and about the possibility of these poor visibility problems over the area.

And we went ahead and showed you over here, this is the circle that you see right there, the area most affected by the quake. And you can see that most of the moisture is actually moving northward, but this doesn't mean that it's not raining there. Light rain or drizzle, which is just as bad as any kind of rain that could fall here, especially for people still living outside. And like I said for any kind of rescue that may still be ongoing or just that bring supplies into the region.

I think Wednesday will be the last -- or the most of the rainy part that we'll see and then start Drying out as we head into Thursday then Friday, which is definitely some good news there.

You can see it again here one more time. The moisture right into that region right in there. Everybody else pretty much staying dry. Even though right now, by the way, it has been raining in Beijing. I've seen a few reports of some rain showers coming through across these areas actually farther to the north. That hasn't helped too much for the air quality problems for you guys in Beijing. Today, you're already up into the 300s earlier. You're back down to the 270, 280 level which is still considered very unhealthy. We need some rain here. That hasn't exactly happened. And we're not expecting any rain any time soon.

Kristie, back to you.

LU STOUT: All right. Mari Ramos there, thank you.

And before we go, we want to say happy birthday to YouTube. The video sharing site turns eight today and although you'd be forgiven for thinking it's older, given the impact it has had.

Now this, we bring it up for you, is the very first YouTube video posted April 23, 2005. It shows Jawed Karim, the sites co-founder, at the San Diego zoo. Now, he and his business partners, they sold YouTube to Google the following year for a whopping $1.65 billion.

And when it comes to YouTube, thinking in billions is quite appropriate. After all, the South Korean pop star Psy recently became the first person to get a billion hits for a video, that's for his song Gangnam Style. And his new video Gentleman has set the record for the most views ever in a single day.

And whether you're into cute cat videos or want to check out the latest movie trailers, you're certainly not alone. YouTube says it gets a billion unique users every month. That means if the site was a country it would be the third biggest in the world. Not bad for an eight year old.

And that is News Stream, but the news continues at CNN. World Business Today is next.
