An American soldier most likely acted out of resentment when he threw grenades //into// three tents at a United States Army command center in Kuwait, killing a fellow serviceman, Army officials said.

　　Fifteen other soldiers, including the brigade commander, were wounded - at least three of them seriously - in the early Sunday attack at Camp Pennsylvania, the rear base for the 101st Airborne Division near the Iraqi border. The 101st, a 22,000-member rapid deployment unit, is based at Fort Campbell, Kentucky.

　　Army Capt Christopher Scott Seifert, 27, was killed in the attack while sleeping in his tent, the Defense Department said. Seifert's parents declined comment, a family spokesman said.

　　The soldier in custody was identified as Sergeant Asan Akbar of the 326th Engineer Battalion, who was found hiding in a bunker after the attack, officials said.

　　Akbar, who as a sergeant commanded four to seven soldiers, had not been charged, Fort Campbell spokesman George Heath said. If he is found guilty of any crime, he would be brought back to Fort Campbell "for judicial punishment," Heath said.

　　He added that Akbar had been "having what some might call an attitude problem." He did not say how long Akbar had served in the military.

　　Another Army spokesman, Max Blumenfeld, said the motive in the attack "most likely was resentment." No further details were available.

　　But Akbar's mother, in an interview with Nashville newspaper The Tennessean, said he had long feared persecution by his fellow troops for being a Muslim. He also had said he had been recently reprimanded for insubordination.

　　"He said, 'Mama, when I get over there I have a feeling they are going to arrest me just because of the name that I have carried,"' Quran Bilal was quoted as saying.

　　The attack happened in the command center of the division's 1st Brigade at Camp Pennsylvania.

　　One grenade went off in the command tent, Blumenfeld said. The tent, the tactical operations center, runs 24 hours a day and would always be staffed by officers and senior enlisted personnel.

　　Colonel Frederick B. Hodges, commander of the 1st Brigade, was slightly injured.

　　Initially, the military suspected the attack was the work of terrorists using two grenades and small-arms fire, Heath said. Two Middle Eastern men hired as contractors were detained and released.
