Abu Anas al-Libi said he was abused physically and psychologically aboard an American ship for a week before making them.
A written declaration signed by al-Libi last month was publicly released this week. He said he was falsely charged in the bombings in Kenya and Tanzania, which killed 224 people, including a dozen Americans.
Al-Libi, 50, who was snatched from the streets of Tripoli a year ago, said he was convinced that torture at a CIA-run site awaited him after spending his first night in custody on a hard floor, handcuffed and in leg irons, with ear muffs and a blindfold on his head.
“I felt I would never see my family ever again,” he said. “I lived in morbid fear of my imminent death where its only precursor would be torture.”
Al-Libi said he was taken to the USS San Antonio in the Mediterranean, where he was subjected to daily interrogation by CIA agents who warned him that the questioning would be the “easiest step” of three.
“I took this to mean that the physical and psychological torture would only increase if I failed to co-operate with my questioners,” said al-Libi, who is also known as Nazih Abdul-Hamed al-Ruqai.
“These threats continued the entire time I was on board the ship.”
Al-Libi, once on the FBI’s list of most wanted terrorists, said he was kept in a lighted windowless room with no bed or chair when he was not being interrogated until he was flown to America on a plane with FBI agents and an interpreter.
“After having been subjected to the treatment above, and being confused and disoriented, with no understanding of where I was, or what would happen to me, I gave the statement the FBI has,” he wrote.
“I felt the only way to be treated fairly and humanely was if I did what I was told.”
He said he felt betrayed after he “joined with forces of Nato and the United States” to help replace former Libyan leader Muammar al-Gaddafi in 2010 and 2011, hoping to establish a “stable Islamic secular state” in Libya.
The US government said al-Libi’s arguments were meritless because his rights were explained to him before he spoke.
“The defendant does not make a single specific factual allegation that the law enforcement agents took any steps to coerce him into waiving his Miranda rights,” prosecutors said, in reference to the statement read to all suspects when they are arrested by US police.
“He does not allege that anyone shouted at or threatened him. He does not allege that anyone injured him or that any weapons were displayed. He does not allege that he was fearful of the law enforcement officers who advised him of his Miranda rights.”
Al-Libi has pleaded not guilty to conspiracy charges in the embassy bombings case. The defence’s court filing included a heavily redacted version of his statements, in which he said he was tired and needed rest.
