A Yemeni man, Khaled al-Maqtari was reportedly held in CIA prisons known as 'black sites' for more than 2 years. He was arrested in 2004 in Falluja, Iraq on the suspicion of being an insurgent.

Although Bush banned "cruel, inhuman or degrading treatment" of terrorist suspects in 2007, he has also admitted previously to the existence of black sites (in Eastern Europe) and the CIA has not remarked on the issue.

Amnesty International has apparently been in contact with al-Maqtari and the organization has noted the existence of flight records which may correspond with the dates he would have been transferred. Amnesty also reports his claims of torture while in the jail.
