The attack comes days after an apparent suicide bombing at the largest US base in the country, which just observed the 15th anniversary of operations against the war on terror.
Four Americans were killed in the attack early Saturday at Bagram Airfield, US Defense Secretary Ash Carter said.
Two of those killed were service members, and two were contractors, Carter said, adding he was "deeply saddened" by the news.
