The Guardian reports:

British officials said today there was no evidence to support claims by George Bush, the former US president, that information extracted by “waterboarding” saved British lives by foiling attacks on Heathrow airport and Canary Wharf. In his memoirs, Bush said the practice – condemned by Downing Street as torture – was used in CIA interrogations of Khalid Sheikh Mohammed, the alleged mastermind of the 9/11 attacks on the US.

He said Mohammed, below, was one of three al-Qaida suspects subjected to waterboarding. “Their interrogations helped break up plots to attack American diplomatic facilities abroad, Heathrow airport, and Canary Wharf in London, and multiple targets in the United States,” he wrote.

It is not the first time information extracted from Mohammed has been claimed as helping to prevent al-Qaida attacks on British targets. Mohammed cited attacks on Heathrow, Big Ben and Canary Wharf in a list of 31 plots he described at Guantánamo Bay after he was subjected to waterboarding 183 times following his capture in Pakistan in March 2003. The Heathrow alert in fact happened a month before his arrest, with army tanks parked around the airport, in what was widely regarded as an overreaction.

British counter-terrorism officials distanced themselves from Bush’s claims. They said Mohammed provided “extremely valuable” information which was passed on to security and intelligence agencies, but that it mainly related to al-Qaida’s structure and was not known to have been extracted through torture. Eliza Manningham-Buller,head of MI5 at the time, said earlier this year that the government protested to the US over the torture of terror suspects, but that the Americans concealed Mohammed’s waterboarding from Britain. Officials said today the US still had not officially told the British government about the conditions in which Mohammed was held.
