“Several” other US troops and Afghan forces were also injured in the attack, Mujahid claimed.
The US military also confirmed in a statement that an American service member had been “killed in action,” without elaborating on the conditions of his death and his identity.
Reuters said the Taliban had posted photographs of a blood-soaked backpack and the identity card of a US soldier as proof of his death.
The attack is likely to affect the Taliban-US talks, which resumed in Doha, Qatar, early in December. The renewed discussions were put on a “pause” for a few days following yet another bomb attack targeting Bagram Air Base north of the Afghan capital, Kabul, but later started again.
