A suicide attack Saturday on Bagram Airfield near Afghanistan’s capital city of Kabul claimed the lives of two Fort Hood soldiers, the military said Monday.

Sgt. John W. Perry, 30, of Stockton, Calif., and Pfc. Tyler R. Iubelt, 20, of Tamaroa, Ill., died in the attack, which also killed two American contractors

They were assigned to Fort Hood’s Headquarters and Headquarters Company, 1st Special Troops Battalion, 1st Sustainment Brigade, 1st Cavalry Division.

Perry, a recipient of a Purple Heart Medal and a Bronze Star, joined the Army in 2008 and had been assigned to the Sustainment Brigade since August 2014.

He deployed to Afghanistan once before from August 201o to July 2011.

Iubelt joined the Army in November 2015 and had been assigned to the Sustainment Brigade since May.

His decorations also include a Purple Heart Medal and a Bronze Star.

Two days before the attack at Bagram, the German consulate in the northern city of Mazar-i-Sharif was attacked.

Six people died and more than 100 were wounded.

In response to the attacks, the U.S. Embassy in Afghanistan was “closed four routine services” Sunday “as a temporary precautionary measure.”

The insurgency in the country has become more virulent since most international combat troops withdrew in 2014.
