Canadian Ex-Gitmo Detainee to Appeal Convictions A Canadian man who spent 10 years at the U.S. military prison in Guantanamo Bay plans to appeal his U.S. terrorism convictions. Omar Khadr's lawyer Dennis Edney says the Toronto-born 26-year-old is "looking forward" to the appeal, which is expected to be filed "very soon." Khadr, the last Western detainee at Guantanamo, was transferred last September to a maximum security facility in Ontario. The son of an alleged al-Qaida financier, Khadr pleaded guilty in 2010 to several charges, including killing a U.S. solider in Afghanistan when he was 15. He was eligible to return to Canada from Guantanamo Bay last October under terms of a plea deal. Edney said Saturday that the defense team will first file an appeal with a U.S. military commission.
