WASHINGTON — A soldier from Maryland died Tuesday after being hospitalized for injuries from a Nov. 12 bombing in Afghanistan.

The Department of Defense announced Wednesday that Sgt. First Class Allan E. Brown, 46, of Takoma Park, died at Walter Reed National Medical Center in Bethesda. He had been hospitalized for injuries from a suicide bomb attack at a U.S. airfield in Bagram, Afghanistan.

The Taliban claimed responsibility for the attack, which they said was carried out by a suicide bomber inside the base. A spokesman for the insurgent group said the attack had been planned for four months.

Two other soldiers — Sgt. John W. Perry, 30, of Stockton, California, and Pfc. Tyler R. Iubelt, 20, of Tamaroa, Illinois — and two American contractors were killed in the explosion. More than a dozen U.S. service members and one Polish soldier had been injured.

Brown had been assigned to Headquarters and Headquarters Company, 1st Special Troops Battalion, 1st Sustainment Brigade, 1st Cavalry Division, Fort Hood, Texas.

Brown had supported Operation Freedom’s Sentinel.
