July 7, 2005: 52 Killed in ‘7/7’ Bombings in London; Three Subway Trains and One Bus Are Hit

England suffers its worst terrorist attack when four bombs go off in London during the morning rush hour. At 8:50 a.m. bombs go off on three London Underground trains within 50 seconds of each other. A fourth bomb goes off at 9:47 a.m. on a double-decker bus, near Tavistock Square. Fifty-six people, including the four bombers, are killed. The bombings become popularly known as ‘7/7.’ [Daily Telegraph, 7/7/2005; Daily Mail, 7/8/2005; CNN, 7/22/2005] The alleged bombers, all British residents between the ages of 18 and 30, are Mohammad Sidique Khan, Hasib Mir Hussain, Shehzad Tanweer, and Germaine Lindsay. All were British nationals of Pakistani descent, except Lindsay, who was born in Jamaica, but moved to England when he was five. [Daily Telegraph, 7/16/2005; BBC, 7/21/2005] In 2004, Khan had been the subject of a routine threat assessment by the British intelligence agency MI5, after his name came up during an investigation into an alleged plot to explode a truck bomb in London. However, MI5 did not consider him a threat and did not place him under surveillance. [BBC, 7/17/2005; London Times, 7/17/2005] According to the Independent, Tanweer had similarly been scrutinized by MI5 that year, but was also not considered a threat. [Independent, 12/17/2005] Khan and Tanweer had flown to Pakistan together in November 2004, returning together in February 2005. However, what they did during their stay is unclear. [BBC, 7/18/2005; CNN, 7/20/2005] Less than a month before the bombings, the British government lowered its formal threat assessment one level, from “severe general” to “substantial,” prompted by a confidential report by the Joint Terrorist Analysis Centre (JTAC). JTAC, which is made up of 100 top intelligence and law enforcement officials, concluded, “At present there is not a group with both the current intent and the capability to attack [Britain]” (see Mid-June 2005). [New York Times, 7/19/2005; London Times, 7/19/2005] The attacks also coincide with the G8 summit in Gleneagles, Scotland, attended by British Prime Minister Tony Blair and US President George W. Bush, amongst others. [Guardian, 7/7/2005] Consequently, 1,500 officers from London’s Metropolitan Police, including many anti-terrorist specialists, are away in Scotland as part of the force of 12,000 created to police the event.
