Diego Garcia was rumoured to have been one of the locations of the CIA's black sites in 2005. Khalid Sheikh Mohammed is one of the "high-value detainees" suspected to have been held in Diego Garcia. In October 2007, the Foreign Affairs Select Committee of the British Parliament announced that it would launch an investigation of continued allegations of a prison camp on Diego Garcia, which it claimed were twice confirmed by comments made by retired United States Army General Barry McCaffrey. On 31 July 2008, an unnamed former White House official alleged that the United States had imprisoned and interrogated at least one suspect on Diego Garcia during 2002 and possibly 2003.
