ERBIL, Iraq (Reuters) - Kurdish security force snipers fired on Monday at gunmen who shot their way into the governorate of Erbil, capital of Iraq’s semi-autonomous Kurdistan region in the north, and took over the building’s third floor, security officials said.

It was not clear how many gunmen were inside. Earlier, security officials said one of them carried out a suicide bombing. More reinforcements and armored vehicles were deployed around the building in a commercial district.

There was no immediate word on casualties.
