[JURIST] Lawyers for Omar Khadr [CBC Khadr family profile], an 18-year old Canadian citizen and Guantanamo Bay detainee, said Wednesday that their client had been tortured and abused by US interrogators. Khadr is accused of throwing a grenade that killed a US medic while he was alledgedly fighting with the Taliban, planting mines in the way of US convoys, and gathering surveillance. He was captured when he was 15 years old and tranferred to Guantanamo Bay [official Navy base website] when he was 16 years of age. Muneer Ahmad, a US attorney for Khadr, said Khadr was short-shackled by the hands and feet and bolted to the floor in painful and degrading positions for long periods of time. Khadr urinated on himself and on the floor and claims he was dragged across the ground as a "human mop." He has yet to be formally charged with any crime. AP has more.
