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 it.
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.
“Response teams at Bagram continue to treat the wounded and investigate the incident.”
Bagram airfield, close to Kabul, has frequently come under attack by Taliban fighters.
Al Jazeera’s Abdullah Shahood, reporting from Kabul, said the base is a heavily guarded area where people only with an exclusive access can enter.
“An Afghan police official told us that the person who got in with the explosives must be a dual citizen and someone who has an access pass and is trusted to go without escort,” he said.
