CIA 'torture': Inside the 'blackout box'
The CIA tortured terror suspects in its programme of "enhanced interrogation", the agency's former executive director, Buzzy Krongard, has admitted to the BBC's Panorama programme.
The agency's position has always been that the "enhanced interrogation" techniques it used under George W Bush, did not amount to torture, because they were legally approved by the White House at the time.
President Obama closed the CIA's programme down when he came to power in 2009.
BBC Panorama reporter Hilary Andersson experiences what it is like inside a "blackout box" as used by CIA interrogators.
