ISTANBUL, Turkey (CNN) -- Powerful explosions ripped through the British Consulate and a London-based bank near a popular shopping area Thursday in Istanbul, killing at least 27 people and wounding more than 450 others, Turkish officials said.
Seventeen people were killed at the consulate and 10 in the shopping area in the neighborhood of Levent, the Turkish Interior Ministry said.
Consul General Roger Short was among those killed, said Ian Sherwood, chaplain of the British Consulate. One of the main buildings was "completely demolished," he said.
It was the second coordinated attack in Istanbul in the last week. On Saturday, suicide car bombers killed 23 people at two synagogues. (Full story)
Video from the scene of Thursday's attacks showed shattered windows along the narrow streets near the consulate and some areas reduced rubble.
People could be seen trying to remove debris by hand from around buried cars as rescuers with search dogs searched for survivors.
Another blast, outside an HBSC bank, ripped the facade off the tall building. Video of a nearby shopping mall showed chaos with people streaming out of the area, some with bloody faces and blood-soaked clothes. Shattered glass and burned vehicles littered the street. (Full story)
Sherwood said the consulate had been "secure as possible" but that the bombing was "huge." He said his house down the street shook, and the whole neighborhood was damaged.
Turkish officials said that bombing, in the Levent neighborhood, occurred shortly before 11 a.m. (4 a.m. EST).
Witnesses said they thought suicide attackers used explosive-packed vehicles.
A spokesman for Britain's HBSC bank said two of the bank's buildings were struck.
"They seem to be organized international terrorism," Turkish Foreign Ministry Spokesman Huseyin Dirioz said following Thursday's attacks. Dirioz said his government will "fight against all sorts of international terrorists."
Al Qaeda, Turkish group claim responsibility
Interior Minister Abdulkadir Aksu told reporters there were similarities between Thursday's attacks and Saturday's car bombings of the two synagogues.
"Probably some trucks were used in carrying explosives" Thursday, Aksu said.
Local officials said the attacks seem to have been substantially larger than Saturday's.
Shortly after Thursday's bombings, a government office in Istanbul received a phone call claiming to be from al Qaeda and a Turkish Islamic militant group -- the Great Eastern Islamic Raiders' Front (IBDA-C) -- claiming joint responsibility, CNN Turk reported. (Expert: Al Qaeda to blame)
IBDA-C also claimed responsibility for the synagogue bombings. But Turkish officials said the synagogue attacks were carried out by two Turkish nationals linked to a group in Afghanistan that may have ties to al Qaeda.
Aksu warned against speculation on which group is responsible for the attacks, saying that could hamper the investigation. (Full story)
Speaking in London, British Foreign Secretary Jack Straw called the attacks "appalling acts of terrorism" that have "all the hallmarks" of an al Qaeda attack.
In Washington, Attorney General John Ashcroft said the attacks "appear to be in the method of operation, the operational style of al Qaeda or al Qaeda operatives or affiliates."
He said the FBI has offered through the State Department to assist Turkish law enforcement authorities in the investigations.
President Bush was in London on a state visit. At a joint news conference, he and British Prime Minister Tony Blair condemned the blasts and vowed to defeat terrorism.
"Cruelty is part of their strategy. The terrorists hope to intimidate. hey hope to demoralize," Bush said. "They're not going to succeed. Great Britain, America and other free nations are united today in our grief and united in our determination to fight and defeat this evil wherever it is found."
Said Blair: "We must affirm that in the face of this terrorism there must be no holding back, no compromise, no hesitation in confronting this menace, in attacking it wherever and whenever we can, and in defeating it utterly." (Full story)
The blast outside the HSBC bank building ripped off the structure's facade.
A White House spokesman said Washington is monitoring the situation.
Straw told the House of Commons that the country is taking measures to step up security at facilities at home and abroad.
In New York, the United Nations Security Council unanimously passed a resolution condemning the bombings.
The resolution speaks of the "need to combat by all means" threats to international peace and security caused by terrorist acts and asks all states to "cooperate in efforts to find and bring to justice the perpetrators, organizers and sponsors of these terrorist attacks."
Aksu said Turkey was banning media coverage at the sites "to investigate the incident more properly." It was not clear how much coverage would be curtailed.
The United States and Britain warned their citizens to proceed cautiously in Istanbul after the attacks. (Full story)
