KABUL - American military officials say a member of the Utah National Guard has been killed in an apparent “insider attack”' in the capital of Afghanistan.

Sgt. 1st Class Debra Richardson, a Resolute Support spokeswoman, said Saturday in a statement that another U.S. service member was wounded in the attack.

A statement from a spokeswoman for the NATO-led Operation Resolute Support says the attacker was a member of the Afghan security forces and that initial reports indicate the assailant was immediately killed by other Afghan forces.

The two U.S. service members were medically evacuated to Bagram Airfield, where the wounded service member is undergoing medical treatment and is in stable condition, it said.

The incident is under investigation.

The Utah National Guard has identified the service member killed as a member of the Guard. The Guard member's name is being withheld pending notification of next of kin.
