A service member was killed and two were wounded in Afghanistan on Monday in what appears to be an insider attack, the NATO Resolute Support coalition said.

The attack occurred in Herat province in western Afghanistan and initial reports indicate it was committed by a member of the Afghan security forces, according to a coalition press release. Pentagon spokesman Col. Rob Manning said the service member was not American.

The killing comes just days after the Taliban claimed responsibility for an attack in Kandahar that wounded a U.S. one-star general and killed two senior Afghan officials.

That earlier shooting on Thursday at the Kandahar governor’s compound also allegedly targeted the top American commander in the country, Gen. Scott Miller, who heads U.S. Forces-Afghanistan.

The Washington Post on Sunday quoted several sources saying that Brig. Gen. Jeffrey Smiley was wounded in the attack. U.S. Forces-Afghanistan originally said three were wounded: one U.S. service member, one civilian and one foreign contractor.
