Attahullah Khogyani, a spokesman for the provincial governor in Nangarhar province, said that two other U.S. soldiers were also wounded in the attack. The Afghan soldier who opened fire was killed after the attack, which took place in the Achin district.
White House Deputy Communications Director Raj Shah said President Trump had been informed of the situation. The U.S. military has not commented.
Such insider attacks have happened before in Afghanistan. In March, another Afghan soldier was killed after he opened fire on foreign forces at a base in Helmand province, wounding three U.S. soldiers.
