Prosecutors: Guantanamo Bay inmate took pride in slaying

GUANTANAMO BAY NAVAL BASE, Cuba — A Canadian former child soldier told jailers he comforted himself in his first days at Guantanamo by thinking about killing an American soldier, military prosecutors said Thursday in opening arguments at the war-crimes trial of the youngest inmate at the detention center.
Toronto-born Omar Khadr, who was 15 when he was captured in 2002, is accused of throwing a grenade that killed a Delta Force medic after a firefight in Afghanistan.
"Omar Khadr is a terrorist, trained by al-Qaida to murder Sgt. 1st Class Christopher Speer," prosecutor Jeff Groharing told a jury of US military officers inside a hilltop courthouse at this US Navy base in southeast Cuba.
Khadr denies throwing the grenade, and his lawyers argued that his purported confessions were extracted through mistreatment, including threats of rape.
