A Guantanamo bay convict claims he was forced to have sex with female interrogators in his recently published memoir.

Detainee Mohamedou Ould Slahi joined the terrorist organisation Al- Qaeda in the 1990s soon after the Russian occupation of Afghanistan and was taken to the Cuban prison in 2002.

Slahi - or prisoner 760 - recalled in his memoir how interrogators told him they would teach him about “great American sex” and was later forced to have sexual intercourse with three female interrogators.

In the redacted version of his book, the inmate claims his captors took off their tops and 'talked dirty' to him before touching him, according to The Mirror.

“What hurt me most was them forcing me to take part in a sexual threesome in the most degrading manner. What many _______ don’t realize is that men get hurt the same as women if they’re forced to have sex, maybe more due to the traditional position of the man,” wrote Salahi, as reported by The Independent.

Slahi’s handwritten manuscripts became the first published book written by a current inmate of the controversial prison held by the American military.

In his book, for which he had to struggle for six-years to get it published, Slahi recounts the physical and mental torture, brutal treatment and humiliation that he had to suffer during his time at the prison that currently holds 122 inmates .

The 44-year-old alleges he was repeatedly beaten, forced to drink salt water and even kept in a “frozen room” for hours. He states in his book that the maltreatment and torment haunted him.

According to The Independent, Slahi claims he was denied sleep for over two months during his brutal interrogation. “For the next 70 days I wouldn’t know the sweetness of sleeping: interrogation 24 hours a day, three and sometimes four shifts a day,” he says in his book.

The Independent reports how Slahi was once told by a female interrogator: “If you start to cooperate, I’m gonna stop harassing you. Otherwise I’ll be doing the same with you and worse every day...Having sex with somebody is not considered torture.”

The inmate’s lawyer, Nancy Hollander who took his case in 2005 claims Slahi has never been charged with any crime and that her client’s brutal treatment in the prison is the result of “enhanced interrogation techniques” being employed by the Central Intelligence Agency (CIA).

Guantanamo Bay’s treatment of inmates has triggered debates in the past and pressure has been exerted on the American government to shut the prison which was opened in 2002.
