(CNN) The mayor of a small Utah city was killed Saturday in Kabul, Afghanistan in small arms fire while serving in the Army National Guard.

On Sunday, the Pentagon confirmed the identity of Brent Taylor of North Ogden.

Reports indicated the attacker was a member of the Afghan National Defense and Security Forces and was immediately killed by other Afghan forces, the NATO-led Resolute Support coalition said. The Defense Department said the incident is under investigation.

Taylor was elected to the city council of North Ogden, about 45 miles north of Salt Lake City, in 2009 and became mayor in 2013, according to the city council website.
