Immediately following the attacks, London police began examining about 2,500 hours of Closed Circuit Television (CCTV) footage from security cameras at the scenes of the attacks. It is now known that the four suicide bombers, each with a backpack full of explosives, met at Luton, Bedfordshire, to take the train to London, separating at King’s Cross station at around 8:30 a.m.
In the months after the attacks, police reported that the bombers were "home-grown," middle-class British citizens. Germaine Lindsay was a Jamaican-born British resident who lived in Aylesbury, Buckinghamshire; Mohammed Sidique Khan, Hasib Hussain and Shehzad Tanweer were British nationals of Pakistani descent living in or near the city of Leeds, West Yorkshire.
Though there was no public inquiry into the July 7 bombings, the British government released an official report on May 11, 2006, concluding that the July 7 bombers had used information on the Internet to construct the bombs, which were made with readily available materials. The implementation of their plan had been "simple and inexpensive." The report also stated there was, "as yet no firm evidence to corroborate this claim or the nature of Al Qaida support, if there was any. But, the target and mode of attack of the 7 July bombings are typical of Al Qaida and those inspired by its ideologies."
After the 2004 bombings in Madrid and the 2005 London bombings, news reports pointed to the new threat from al-Qaeda inspired semi-autonomous groups throughout Europe.
On July 21, 2005, a similar attack was attempted by an unconnected group, but failed. Three bombs secreted onto the Underground and one bomb onto a London bus all failed to detonate, and there were no casualties. All suspected bombers escaped the scene but were later arrested.
On April 5, 2007, three men were charged in connection with the July 7 attacks. Mohammed Shakil, 30, and Shipon Ullah, 23, were arrested in Manchester as they were boarding a flight to Pakistan. Sadeer Saleem, 26, was arrested at the residence of one of the deceased suicide bombers in Leeds.
Globally, people watched the aftermath of the attacks in shock and horror. On July 8, 2005, U.S. President George W. Bush visited the British Embassy in Washington, D.C., and signed a book of condolence, one of many created in British embassies and consulates around the world. Outside, the U.S. Army band played "God Save the Queen" (just as Britain had played "The Star-Spangled Banner" in front of Buckingham Palace after September 11, 2001) as visitors left messages, flowers and tributes.
Almost one week later, a two-minute commemorative silence for the victims of the London bombings was observed throughout Europe.
Terror-alert levels were quickly raised in the UK, Canada, France, Germany and the United States, among others. Public transport systems were under particularly intense security.
“I'm from Madrid. Last Thursday we had that horrible feeling again. Seeing our brothers in London coming out from the subway, we cried again, we felt deep pain again. But they know we're together. We're stronger now. They know they will never win us."
Guillermo Ramos, Madrid, Spain, user e-mail to CNN.com, Friday, July 15, 2005
One year after the attacks on July 7, 2006, the United Kingdom observed two minutes of silence at midday to remember the victims. A memorial service was held at each of the four bombing locations and plaques were unveiled at the tube stations that were sites of the attacks.
On February 3, 2007, the Department for Culture, Media and Sports in the United Kingdom announced that a permanent memorial to commemorate the 52 people who lost their lives would be located in Hyde Park, on Lover’s Walk, chosen for its central location and its history. The memorial will be designed by Ove Arup and Partners Ltd, in partnership with Carmody Groarke and Colvin and Moggridge Ltd.
The National September 11 Memorial & Museum offers our condolences to the families of the victims who were killed in London. We stand in solidarity with the survivors who lived through this senseless attack. While we remember the tragedy, we also must remind ourselves that the humanity that binds us is stronger than the hate that seeks to divide us.
