Memos which shed light on the “extreme interrogation” of terror suspects at detention centres like Guantanamo Bay have been released by White House officials.
The four documents, sent to the CIA between 2002 and 2005 by officials in the Bush administration, approve waterboarding – making the suspect feel like they are drowning – sleep deprivation, nudity and putting insects in with a tightly confined prisoner, as well as slapping and shoving suspects against a wall.
