A US marine was killed and four others wounded during a new year’s day combat operation in Afghanistan.

According to the NATO mission in Kabul, the “combat engagement” occurred in Achin, in the restive Nangarhar province in Eastern Afghanistan.

The two wounded service members are being treated at a nearby medical treatment facility and are in stable condition.

The other service members have returned to duty.

While Afghan security forces are conducting most of the fighting against the Taliban and other insurgent groups, US troops operate alongside them in a training capacity and are frequently on the front lines.
