Ex-Gitmo Detainee Transferred After Threat The lawyer for a Canadian man who spent 10 years at the U.S. military prison at Guantanamo says his client has been transferred from a prison in Ontario to one in Western Canada after another inmate threatened his life. Omar Khadr, the last remaining Western detainee at Guantanamo, was repatriated to Canada last September to serve out the remaining six years of his sentence. The Toronto-born son of an alleged al-Qaida financier, Khadr pleaded guilty in 2010 to killing a U.S. solider in Afghanistan when he was 15. Attorney Dennis Edney says Khadr was serving meals at Ontario's Millhaven prison when an inmate threatened to stab him after he refused him more butter than he was entitled to. Alberta-based Edney says Khadr was transferred to an Alberta prison Tuesday.
