A Maryland soldier who was injured after a suicide bomber attacked Bagram air base in northern Afghanistan last month has died, authorities said Wednesday.

Sgt. First Class Allan E. Brown, 46, of Takoma Park died Tuesday at Walter Reed National Medical Center in Bethesda, the Department of Defense said in a statement.

Brown, who was assigned to Headquarters and Headquarters Company, 1st Special Troops Battalion, 1st Sustainment Brigade, 1st Cavalry Division, at Fort Hood, Texas, was injured on Nov. 12 by an improvised explosive device at Bagram, the statement said.

The suicide attack, which reportedly occurred during a “fun run” at the base, killed two U.S. service members that day, two American civilian contractors, and injured 17 other people.

The suicide bombing was the first at Bagram since it opened to U.S. troops in 2001.

Brown entered the service in 2004 as a senior data systems integrator, Fort Hood said in a statement. He was deployed in Operation Iraqi Freedom from August 2006 to August 2007, November 2008 to October 2009, and December 2010 to December 2011, the statement said.

Brown also was deployed in support of Operation Enduring Freedom from July 2014 to September 2014, and in Operation Freedom’s Sentinel from September to December 2016, according to the statement.

Brown earned several medals, including five Army Commendation Medals.

Also killed in the incident were Sgt. John W. Perry, 30, of Stockton, Calif., and Pfc. Tyler R. Iubelt, 20, of Tamaroa, Illinois. Both died on Nov. 12.
