NATO said an attack in eastern Afghanistan has killed one of its service members, according to the Associated Press.

A statement from the U.S.-led coalition says the soldier died after coming under direct fire by enemy forces on Monday, Dec 23.

The coalition, known as the International Security Assistance Force, provided no other details or the nationality of the killed soldier.

Afghan insurgents have increased attacks in recent months, intensifying a campaign to regain territory as foreign forces draw down ahead of a full withdrawal at the end of 2014.

Monday's death brings to eight the number of coalition deaths so far this month. Last Tuesday, six U.S. soldiers died when their Black Hawk UH-60 went down during a mission in Zabul, southern Afghanistan.
