CIA Used UK territory for secret terror interrogations - top US official

CIA did use United Kingdom territory for secret terror interrogations, says top US official - Americas - World - The Independent

It is the first time that a top Bush administration official has gone on the record to state that the British territory formed part of the chain of “black sites” from Poland to Afghanistan used by the CIA for interrogation and torture.
In an interview with the Vice News website, Mr Wilkerson said that Diego Garcia did not host a permanent CIA prison but was used as a back-up location to conduct interrogations and it was “difficult” to believe they could have taken place without the knowledge of the British authorities.
