The former head of Britain's domestic intelligence service, MI5, has accused the United States of concealing its mistreatment of terror suspects.
Eliza Manningham-Buller said Tuesday that the U.S. deliberately held back details of harsh handling of some detainees, including the waterboarding of alleged September 11 mastermind Khalid Sheikh Mohammed.
Manningham-Buller's comments come as the British intelligence service fights charges it collaborated with U.S. agencies in torturing terror suspects.
British appeals court judges ordered the government last month to release documents concerning the treatment of a Guantanamo inmate Binyam Mohamed, an Ethiopian-born man living in Britain.
U.S. forces arrested him in Pakistan in 2002 on suspicion of terrorism. U.S. documents show that Mohamed was shackled, beaten and subjected to genital mutilation and sleep deprivation while held in Morocco and later at Guantanamo.
The British government had said it wanted to keep the information secret, fearing it could hurt intelligence-sharing with the United States.
