A military jury sentenced a soldier to death Thursday for a grenade and rifle attack on his own comrades during the opening days of the Iraq invasion, a barrage that killed two officers and that prosecutors said was driven by religious extremism. Sgt. Hasan Akbar, who gave a brief, barely audible apology hours earlier, stood at attention between his lawyers as the verdict was delivered. He showed no emotion. He could have been sentenced to life in prison with or without parole for the early morning March 2003 attack, which also wounded 14 fellow members of the Army's 101st Airborne Division at Camp Pennsylvania in Kuwait, the Associated Press reported.
