Suicide bombers stormed a gas facility in northern Iraq on Sunday and clashing with police guards, security sources said.

It was not immediately clear if security forces had managed to regain control of the AB2 gas compressor station, about 15 km (10 miles) northwest of Kirkuk. There were expected to be casualties among the police and personnel at the site.

There was no immediate claim of responsibility for the attack, but Islamic State militants have previously targeted oil facilities in the area with explosives. – Reuters
