In January 2008 there were approximately 285 detainees.

Abdurahman Khadr
Abdurahman has described himself as the "black sheep" of his family, who was disgusted by the celebrations he witnessed of the attacks on September 11, 2001. He reported that he cooperated fully with the Americans, eventually agreeing to serve as a mole for the CIA, first in Guantanamo Bay detention camps, and later in Bosnia, where he was tasked to win the trust of Arab veterans of the Bosnian War of Independence.

Omar Khadr
Omar was captured after a skirmish in Afghanistan on July 27, 2002, where he was accused of throwing a grenade which fatally wounded Christopher Speer, an American Special Forces Sergeant.
