Salim Ahmed Hamdan, a former driver for Osama bin Laden in Afghanistan who faces a historic military trial next week, testified Tuesday before the war court at the U.S. Navy base in Guantanamo Bay, Cuba, describing isolation, sleep deprivation and sexual improperness during the almost seven years of captivity. Hamdan, the prisoner who challenged George W. Bush and won, said during the first pre-trial hearing that a female interrogator at the Guantanamo Bay prison extracted information from him using sexually suggestive behavior, calling it "improper."

The Yemen native, who is accused in a terrorism conspiracy, told the military court that during questioning in 2002 a woman interrogator "came close to me, she came very close, with her whole body towards me. I could not do anything. I was afraid of the soldiers."

"Did she touch your thigh?" asked Hamdan’s attorney, Charles Swift.

"Yes…I said to her, ‘What do you want?’" said Hamdan. “She said, 'I want you to answer all of my questions.’ “

"Did you answer all of her questions after that?" Swift asked. Hamdan responded affirmatively.

Hamdan’s lawyers are trying to convince a judge to disregard incriminating statements he supposedly made in front of his interrogators at the U.S. military prison, under the argument that they were acquired by use of intimidation, constraint and force.

His actual trial is set to start Monday. It would be the first military commission led by the U.S. in over a half a century.

In his testimony, Hamdan said he was repeatedly isolated, spending months in confinement, being force-fed, sometimes denied sleep by Guantanamo guards who banged on his cell door every few minutes.

Prosecutors accused Hamdan of conspiring with al Qaeda in terrorist acts and of carrying weapons for the group. Defense attorneys admitted that Hamdan worked as a driver at bin Laden’s farm in Kandahar, Afghanistan, but said he had not been involved in terrorist acts.
