FORT CAMPBELL, Ky. ? The soldier accused in the weekend grenade attack at Camp Pennsylvania in Kuwait was identified today as Sgt. Asan Akbar, 31, an engineer based in Fort Campbell with the 101st Airborne Division.

Akbar allegedly tossed at least two grenades into three tents used to house commanders of the 1st Brigade. The bizarre attack killed Capt. Christopher Scott Seifert, 27, of Easton, Pa., while he was sleeping.

Fifteen soldier were wounded; three remain in serious condition.

A possible motive for the attack remained unclear. Akbar was reportedly disciplined recently in Kuwait for insubordination and was being held back from advancing toward Iraq with his fellow troops from the 1st Brigade.

“He was having what some people might call an attitude problem,” said George Heath, public affairs officer at Fort Campbell.

As a sergeant with Bravo Company of the 326th Engineering battalion, Akbar specialized in clearing land mines, concertina wire and other obstacles for field artillery. He supervised between four and eight soldiers.

Akbar is being held in a detention facility in Kuwait.
