http://www.guardian.co.uk/world/video/2008/jul/15/guantanamo.bay.videoThe secrets of interrogation at Guantánamo Bay prison camp were broadcast for the first time yesterday in grainy footage of a teenage inmate calling for his mother and begging: "Help me, help me."
Yesterday's release of eight minutes of video of Canadian intelligence agents questioning a Canadian detainee, Omar Khadr, marked the first time the public has been able to witness the interrogation of a suspect at the camp.
It also offered a glimpse into the effects of prolonged detention and sleep deprivation on inmates at Guantánamo.
The footage surfaced on a day when the treatment of detainees in the war on terror returned to the spotlight in the US courts, Congress and Guantánamo itself.
In Virginia, a court ruled that the only enemy combatant detained on US soil, Ali Saleh al-Marri, who has been held in a naval brig since his arrest in 2001, had the right to challenge his detention in court.
In Guantánamo, Salim Ahmed Hamdan, accused of being a driver for Osama bin Laden, told a military court that he was held in long and repeated periods of solitary confinement and subjected to humiliation, with a woman interrogator brushing up against his thigh.
Meanwhile, Congress held inquiries into how the Bush administration reached its legal limits on the treatment of prisoners at Guantánamo, with testimony from the official who was once in charge of detainee policy, Douglas Feith.
At the time the video was produced, February 2003, Khadr was 16. He had been subjected to what guards called the "frequent flyer" programme, in which detainees are deprived of sleep.
In Khadr's case, he was prevented from sleeping for more than three hours at a time for 21 days.
In the footage broadcast yesterday, Khadr's despair at his indefinite confinement is palpable. He strips his orange prison uniform over his head, rocks and holds his face in his hands, weeping and begging for help. "You don't care about me," he tells interrogators.
Commentators described his indistinct moans as Khadr saying: "help me", "kill me", or even calling for his mother in Arabic.
The video, which the Canadian government handed over to Khadr's lawyers on the orders of Canada's supreme court, was the first sight of some seven hours of footage of his interrogation by Canadian agents. The images were recorded by a camera hidden in an air shaft as Khadr was questioned over four days.
