Staff Sgt. Ryan Knauss, 23, of Corryton, Tennessee, died from injuries suffered in the attack Thursday near the Abbey Gate entrance to Hamid Karzai International Airport in Kabul, Afghanistan, about 9:10 a.m. Eastern time.

The suicide bombing was followed by gunfire from ISIS gunmen, said Army Maj. Gen. Hank Taylor, deputy director of the Joint Staff for Regional Operations, during a Pentagon press briefing Friday.

Knauss, 23, of Corryton, about 20 miles northeast of Knoxville, was married and had already served a nine-month deployment in Afghanistan. He grew up in Tennessee and joined the Army straight out of high school.

The Department of Defense said in a news release Saturday that Knauss was assigned to the 9th Psychological Operations Battalion, 8th Psychological Operations Group based at Fort Bragg, North Carolina. He was the recipient of the Purple Heart and Bronze Star, among other decorations.

Col. Jeremy Mushtare of the 8th Psychological Operations Group released a statement Saturday saying the loss of Knauss was "devastating to our formation and Army family.”
