NATO says at least four people have been killed in an explosion inside the largest US military base in Afghanistan, with the Taliban claiming responsibility for the attack.
The explosion struck at dawn on Saturday inside the heavily fortified Bagram Airfield, north of Kabul, as the Taliban step up attacks on Western targets before the onset of winter, when fighting usually ebbs.
The nationalities of those killed were not immediately known after the blast, which highlights a worsening security situation nearly two years after NATO formally ended its combat operations in Afghanistan.
"An explosive device was detonated on Bagram Airfield resulting in multiple casualties. Four people have died in the attack and approximately 14 have been wounded," NATO said in a statement, Aljazeera reports.
