Fort Bragg, N.C. ? 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 15-person military jury, which last week took just two and a half hours to convict Akbar of premeditated murder and attempted premeditated murder, deliberated for about seven hours in the sentencing phase. After jurors reached a verdict, they voted on whether to reconsider the decision after one juror asked that they do so.

The sentence will be reviewed by a commanding officer and automatically appealed. If Akbar is executed, it would be by lethal injection.

“I want to apologize for the attack that occurred. I felt that my life was in jeopardy, and I had no other options. I also want to ask you for forgiveness,” Akbar told the jury before it deliberated in the sentencing phase.

Akbar, 34, spoke for less than a minute, delivering an unsworn statement that could not be cross-examined.

While the defense contends Akbar was too mentally ill to plan the attack, they have never disputed that he threw grenades into troop tents in the early-morning darkness and then fired on soldiers in the ensuing chaos. Army Capt. Chris Seifert, 27, and Air Force Maj. Gregory Stone, 40, were killed.

Prosecutors say Akbar launched the attack at his camp — days before the soldiers were to move into Iraq — because he was concerned about U.S. troops killing fellow Muslims in the Iraq war.
