A mass grave has been discovered in the town of Bucha, in the outskirts of the Ukrainian capital of Kyiv, a CNN team found.
Bodies were first buried in the grave, on the grounds of the Church of St. Andrew and Pyervozvannoho All Saints, in the first days of the war, residents told CNN.
CNN saw at least a dozen bodies in body bags pilled inside the grave. Some were already partially covered.
According to residents, more bodies are already buried on site. They said they belong mostly to civilians killed in the fighting around Bucha.
Residents told CNN that around 150 people are buried there.
The mayor of Bucha said in public remarks on Saturday that there could be up to 300 victims buried on site.
CNN was unable to independently verify those numbers or the identities and nationalities of those buried in the grave.
The earth on the church grounds appeared to have been recently moved so it is feasible that a larger number of bodies is buried there.
Bucha has seen some of the heaviest fighting since the war started.
Destroyed Russian vehicles line the streets and most houses have been damaged in some way, with a large portion of the buildings there completely destroyed.
CNN's Senior International Correspondent Fred Pleitgen, producer Vasco Cotovio, producer Daria Markina and photojournalist Byron Blunt also saw people at the site of the mass grave crying and looking for the bodies of lost loved ones.

The northern Ukrainian city of Chernihiv is about 70% destroyed following an assault by Russian troops, Vladyslav Atroshenko, the city’s mayor, said Sunday.
The “consequences” of the attack by Russia in Chernihiv are “severe,” similar to the aftermath in other badly damaged cities and towns like Bucha, where bodies of civilians were found in the streets, as well as in Kharkiv and Mariupol, he said.
The most urgent issues facing residents is a “concentration of Russian troops on the Belarusian border,” and concerns the city will be hit with more missiles and air bombs, Atroshenko added.
“Russians move around Ukraine like at home. And the fact that they left does not mean that they will not come back tomorrow. It takes about an hour and a half for them to get to us ... Today we can say it is quiet, there is cleaning, there is demining," he said.

"This is genocide," Ukrainian President Volodymyr Zelensky said on Sunday, speaking after images emerged of civilian bodies strewn across the streets of Bucha, northwest of the capital of Kyiv, following the withdrawal of Russian forces from the area.
When asked during an appearance on CBS News' "Face the Nation" program if Russia is carrying out genocide in Ukraine, Zelensky replied: "Indeed. This is genocide."
"The elimination of the whole nation, and the people. We are the citizens of Ukraine. We have more than 100 nationalities. This is about the destruction and extermination of all these nationalities," he continued.
Ukraine doesn't want to be "subdued to the policy of the Russian Federation," Zelensky said, adding that this "is the reason we are being destroyed and exterminated."
"This is happening in the Europe of the 21st century. So, this is the torture of the whole nation," the president stressed to viewers.
The alleged atrocities in Bucha have drawn international outrage, with Western leaders calling for war crimes investigations and fresh sanctions on Russia.
US Secretary of State Antony Blinken said Sunday that the State Department would help document any atrocities the Russian military committed against Ukrainian civilians. NATO Secretary General Jens Stoltenberg called the deaths of civilians in Bucha a “brutality" and said “I strongly welcome” an investigation by International Criminal Court, which has opened an investigation into war crimes in Ukraine.
Russia's response: The Russian Ministry of Defense claimed the extensive footage was "fake," saying "not a single local resident suffered from any violent actions," during Russia's occupation of Bucha. "In the settlements of the Kiev region, Russian military personnel delivered and issued 452 tons of humanitarian aid to civilians," it said in a statement.
A separate statement claimed the footage was staged. "Stories about Bucha appeared in several foreign media outlets at once, which looks like a planned media campaign," the statement said. "Taking into account that the troops left the city on March 30, where was the footage for four days? Their absence only confirms the fake."
The Russian government has consistently responded to allegations of civilian casualties inflicted by Russian forces with blanket denials. After the Russian air force bombed a maternity hospital on March 9, Russian officials attempted to cast doubt on widespread media reports, with one Russian diplomat accusing a victim of the bombing — a woman who escaped from the bombing, bloodied and still pregnant — of being an actor and not a real victim.
CNN has not been able to independently confirm the details around the men's deaths. CNN had requested comment from the Russian defense ministry regarding allegations of the execution of civilians in the Kyiv region and other parts of Ukraine.

State Department spokesperson Ned Price hinted at additional US action against Russia coming “very soon” when asked about Ukrainian President Vladimir Zelensky's request for greater G7 sanctions in response to the latest atrocities in Bucha.
"When it comes to our sanctions, we've always said that we will continue applying pressure on President Putin, on the Kremlin, on all of those around him including oligarchs and cronies who are empowering this war of choice against Ukraine, until and unless the Kremlin deescalates, until and unless the violence diminishes, and until and unless these kinds of atrocities come to an end. So I suspect you will very soon see additional pressure applied,” Price told MSNBC Sunday.
"When it comes to these images out of Bucha, we have already assessed that Russia's forces have committed war crimes. What we're doing, we are collecting information. One, to shine a spotlight on precisely what they're doing, but two, to ensure that all of those who have perpetrated these atrocities and all of those who ordered these atrocities are held to account. That's our mission," he continued.
Shocking images came to light from Bucha, Ukraine Saturday by Agence France-Presse of at least 20 civilian men dead and lining a single street. The photos were released the same day Ukraine declared the town liberated from Russian troops. Accounts of alleged Russian atrocities are emerging as its forces retreat from areas near Kyiv following a failed bid to encircle the capital.
CNN has not been able to independently confirm the details around the men's deaths and has requested comment from the Russian defense ministry regarding allegations of the execution of civilians in the Kyiv region and other parts of Ukraine.
Asked about peace talks, Price said, "We have not seen any indication yet that the Russians are truly serious about deescalating this war."
Price also dismissed reports that the Russian ruble is recovering from the sanctions, saying, "This is almost entirely artificial. The ruble is on life support with draconian measures that the Kremlin has been forced to take to artificially prop up the value of the ruble.”
Price noted that the government is preventing Russians and others from selling rubles “precisely to establish this floor and ensuring that the value we see reflected on the market isn't actually the actual worth of the ruble today.”
“When it comes to the Russian economy, 30 years of economic integration have been undone in the past five weeks alone,” Price said.

The US will provide $50 million to help Moldova assist with the impacts of the Russian invasion in Ukraine, including supporting programs training and equipment for border management, and efforts to counter human trafficking, according to a news release.
The US mission said the funding will also provide assistance “to improve accountability and transparency in the justice sector, and combat corruption and cybercrime,” the release said.
“Today, I was able to see firsthand the way your government and the Moldovan people have come together to embrace Ukrainian refugees — most of them women and children — who have been forced to leave behind everything they have and people they love to flee to safety,” UN Ambassador Linda Thomas-Greenfield said at a joint news conference with the Moldovan prime minister.
“You have welcomed them with open arms. And for this, your hospitality and generosity are now known around the world. I want you to know that, in all your efforts, you have a committed partner in the United States. We know that this assistance will go far in your hands,” she continued.
The US funding will also support “key lines of effort of the Moldova Support Conference, taking place April 5 in Berlin, to advance international support for Moldova's resilience and reform agenda,” the US mission said.
According to the US mission, more than $178 million has been provided inside Ukraine, and over $123 million has been given to neighboring countries and the EU to support humanitarian efforts and the host of millions of refugees.

This is not a "real withdrawal of Russian forces," NATO Secretary General Jens Stoltenberg said, warning that attacks in Ukraine will continue.
"What we see is not a real withdrawal. But we see that Russia is repositioning its troops and they are taking some of them back to rearm them, to reinforce them, to resupply them. We should not in a way be too optimistic because the attacks will continue," Stoltenberg told CNN's Chief Political Correspondent Dana Bash on Sunday.
Stoltenberg was speaking in the wake of reports from the Ukrainian government Saturday that the entire Kyiv region had been "liberated" from Russian forces. "Irpin, Bucha, Gostomel and the whole Kyiv region was liberated from the invader," Ukrainian Deputy Defense Minister Hanna Maliar said in a Facebook post.
CNN has not confirmed that the entire Kyiv region has been cleared of Russian troops by Ukrainian forces, but the Ukrainian military has in recent days regained control of suburbs around the capital, which has remained under government control. The Russian military has said it is "de-escalating" around Kyiv.
NATO is also "also concerned about potential increased attacks especially in the in the south and in the east," the alliance's chief said.
"So, this is not a real withdrawal but more a shift in the in the in strategy. Focusing more on the on the south and east," he added.

US President Joe Biden's White House Chief of Staff Ron Klain said the war in Ukraine is “far from over” this morning in an interview on ABC News’ “This Week.”
“I think the Ukrainians are winning the war around Kyiv and in the northern part of the country. And that's tremendous credit to the fighting they've done and to the support that the United States and our NATO allies have provided them. We send weapons into Ukraine almost every single day,” Klain told ABC’s George Stephanopoulos.
Klain continued: “But I think we have to be very clear. I think there's a lot of evidence that Putin is simply taking his troops out of the northern part of the country to redeploy them to the eastern part of the country to relaunch a battle there. So I think there have been victories for the Ukrainians so far, but this war, sadly, is far from over.”
