Toronto ? The attorneys for the lone Canadian held in the U.S. military prison at Guantanamo Bay say they will press the Canadian government to ask that their client be tried in Canada.

Omar Khadr, 19, was charged with throwing a grenade that killed one U.S. soldier and partly blinded another during a firefight in Afghanistan in 2002. He is one of 10 Guantanamo detainees who have been formally charged under the process struck down by the U.S. Supreme Court on Thursday.

Canadian officials have exhibited little enthusiasm for taking on the case of Khadr, who at the time of the firefight was 15, a minor under international law. The Khadr family, which emigrated to Toronto in 1977, has been lionized in Canada by radical Muslims, discomfiting authorities and the larger Muslim community.
