Back in the United States, new details have emerged on the mistreatment of prisoners at Guantanamo Bay. On Tuesday, the FBI released documents chronicling more than two dozen incidents. In one case, guards wrapped a prisoner’s head in duct tape after he chanted the Qur’an. In another incident, a female guard was said to have wiped menstrual blood across a prisoner’s face. Military officials and contractors told investigators Pentagon officials — including former Defense Secretary Donald Rumsfeld — directly approved the interrogation methods. The new documents were released to the American Civil Liberties Union. The ACLU is suing Rumsfeld and other officials on behalf of Guantanamo prisoners who say they were abused.
