Almost two years have passed since President George W. Bush publicly acknowledged the existence of a CIA program in which agency-leased aircraft fly terror suspects between secret prisons and interrogation sites around the world. "This program has helped us to take potential mass murderers off the streets before they have a chance to kill," the President said on Sept. 6, 2006. Since that admission, the White House has declined to elaborate or comment further on the program's specifics, although multiple reports have surfaced regarding the existence of secret facilities in Poland and Romania. According to a former senior American official, it appears another locale can be added to the international roster of interrogation sites -- one both more obscure and potentially more controversial than the alleged sites in Poland and Romania. The source tells TIME that, in 2002 and possibly 2003, the U.S. imprisoned and interrogated one or more terrorist suspects on Diego Garcia, an island in the Indian Ocean controlled by the United Kingdom. The official, a frequent participant in White House Situation Room meetings after Sept. 11 who has since left government, says a CIA counter-terrorism official twice said that a high-value prisoner or prisoners were being held and interrogated on the island. The identity of the captive or captives was not made clear. According to this account, the CIA officer surprised attendees by volunteering the information, apparently to demonstrate that the agency was doing its best to obtain valuable intelligence. According to this single source, who requested anonymity because of the classified nature of the discussions, the U.S. may also have kept prisoners on ships within Diego Garcia's territorial waters, a contention the U.S. has long denied. The White House meetings were also attended by a variety of other senior counter-terrorism officials.
TIME discussed the allegation with Richard Clarke, who served as a Special Advisor to President George W. Bush on the National Security Council dealing with counter-terrorism until 2003 but is not the source for this story. "In my presence, in the White House, the possibility of using Diego Garcia for detaining high value targets was discussed," says Clarke.
