The U.S. military is providing few details of a serious vehicle accident that occurred Monday in Afghanistan’s Nangarhar province, killing one American soldier and injuring eight others.

U.S. military officials will say only the death was the result of a non-combat related incident, but have not released the type of vehicle or any of the circumstances of the accident

“A total of nine soldiers were in the vehicle,” Brig. Gen. Lance Bunch said during a Pentagon briefing Tuesday. “One died of his injuries, two were taken to a medical treatment facility for treatment of non-life-threatening injuries, and six are being evaluated for possible TBI [traumatic brain injury]," he said.

The dead soldier was identified by the Pentagon as 24-year-old Staff Sgt. David Thomas Brabander of Anchorage, Alaska, who was assigned to 3rd Battalion, 509th Infantry Regiment, 4th Infantry Brigade Combat Team (Airborne), 25th Infantry Division, based in Alaska.

When pressed for details by reporters, Bunch said, “It was a non-combat accident. It's currently under investigation. And when we know more, we'll share it with you.”
