KABUL, Nov. 3 (Xinhua) -- A U.S. soldier of the NATO-led Resolute Support (RS) mission was killed and another was wounded after an Afghan soldier turned his weapon against them here on Saturday, sources from the mission confirmed.

"Initial reports indicate the attacker was a member of the Afghan National Defense and Security Forces. Initial reports also indicate the attacker was immediately killed by other Afghan Forces," the military said in a statement.

The statement added that the wounded service member was undergoing medical treatment and was in stable condition.

"The incident is under investigation. The name of the deceased service member will be released 24 hours after next of kin notification," it said.

Additional information will be released as appropriate, the statement noted.

On Sept. 3, one U.S. service member was killed in a suspected insider attack in eastern Logar province.

NATO and U.S. forces completed their combat mission in Afghanistan by the end of 2014 after 13 years of military presence in the country.

However, around 16,000 foreign forces remained in Afghanistan to help Afghan forces in the fields of training, advising and backing them in the war against insurgents.
