CIA admits destroying tapes of terror interrogations
The CIA has admitted destroying video tapes showing the interrogation of suspected Islamic militant leaders.
The intelligence agency says the tapes were destroyed to protect the identity of CIA agents and because they no longer had any value.
However, civil liberties groups say the move was designed to destroy evidence of possible illegal interrogation methods.
The tapes were destroyed in 2005, when the CIA was facing scrutiny about its secret detention programme and the alleged torture of suspects.
