A latest report written by US military investigators has again confirmed multiple incidents of prisoner abuses at the US naval base at Guantanamo Bay which detains hundreds of foreign terrorism suspects.

The report, presented to the Senate Armed Service Committee Wednesday, gave vivid descriptions of how military interrogators treated the suspects at Guantanamo prison.

US Air Force Lt. Gen. Randall M. Schmidt, who led the investigation since January, admitted that a key suspect had suffered from abuses and insults during "creative, persistent and lengthy interrogations".

The key suspect, whose name the military is not willing to disclose, was forced by the interrogators to admit he is a gay and to wear a bra. They even made him dance with another male prisoner and perform like a dog.

The report also found abundant other cases of abuses. In one case, female interrogators sexually insulted prisoners by inappropriately touching them.

Interrogators also threatened a so-called "high-value" prisoner by saying they could do something to his family.

In another case, a detainee's mouth was sealed with a duct tape to stop him from praying.

Sleep-deprivation methods were also used with loud music played to break the prisoners' will.

In the report, investigators recommended the military to review the methods they used in determining the legal status of the detainees at Guantanamo and to use proper interrogation techniques.

However, the investigators said in conclusion that they have not found any case of torture despite many abuses.

"Detention and interrogation operations were safe, secure and humane," it said.

The investigators had recommended the military to reprimand former Guantanamo base commander Army Maj. Gen. Geoffrey Miller for failures in overseeing interrogations, but the proposal was immediately rejected by Gen. Bantz J. Craddock, commander of the US Southern Command who oversees the Guantanamo base.

The military investigation was conducted following disclosure of FBI reports of abuses at Guantanamo last year.

The Guantanamo base currently detains 520 prisoners and most of them were captured during the US war in Afghanistan after the Sept. 11 terrorist attack.

The detainees are classified as "enemy combatants" by the United States and are denied rights accorded to war prisoners under the Geneva Conventions.
