Civil liberties group raises new Guantanamo concerns

Pentagon officials are investigating new allegations by a civil liberties group that military interrogators at the US prison at Guantanamo Bay questioned detainees under the guise of friendlier FBI agents.

The American Civil Liberties Union released emails that showed FBI officials disapproved of the practice and suggested the military interrogators were trying to take advantage of the rapport the FBI had established with some detainees at the prison in Cuba.
