Afghan militants killed a North-Atlantic Treaty Organisation (NATO) coalition force member during an attack on the United States (US) Bagram airbase outside Kabul, NATO said in a statement on Wednesday.
The attack on the main military airfield in Afghanistan took place on Tuesday evening and the nationality of the service member could not immediately be released, a NATO official said.
The NATO statement did not identify which militant group was responsible for the attack, though most of the groups active fall under the broad umbrella of the Afghan Taliban.
Bagram air base, which is guarded by US Marines and partnered forces, frequently comes under rocket attack from militants.
