WASHINGTON- A high-level military investigation into accusations of detainee abuse at Guantánamo Bay, Cuba, has concluded that several prisoners were mistreated or humiliated, perhaps illegally, as a result of efforts to devise innovative methods to gain information, senior military and Pentagon officials say. The report on the investigation, which is still a few weeks from being completed and released, will deal with accounts by agents for the Federal Bureau of Investigation who complained after witnessing detainees subjected to several forms of harsh treatment. The F.B.I. agents wrote in memorandums that were never meant to be disclosed publicly that they had seen female interrogators forcibly squeeze male prisoners' genitals, and that they had witnessed other detainees stripped and shackled low to the floor for many hours.
Although the Pentagon has issued other reports about accusations of abuse in Iraq, Afghanistan and Guantánamo, the new investigation, by Lt. Gen. Randall M. Schmidt of the Air Force, is intended to be the first major inquiry devoted solely to determining what interrogation practices were used at Guantánamo. The investigation was initiated in response to the disclosure of F.B.I. messages that especially concerned Pentagon officials because the bureau's complaints carried great credibility. (MORE)
