At least 11 workers, including two Iranians, were killed when IS militants stormed a power plant north of Kirkuk and then blew themselves up. Multiple explosions meanwhile rocked the city, and gun battles were ongoing, said witnesses in Kirkuk, speaking on condition of anonymity as they were concerned for their safety. Much of the fighting was centered on a government compound in the city. They said the streets were largely deserted out of fear of militant snipers. IS said its fighters targeted the provincial headquarters. The claim was carried by the IS-run Aamaq news agency and could not immediately be verified.

Please Help.
