Militants from the so called Islamic Stated launched a coordinated assault on natural gas plant in northern Baghdad, killing at least 11 people and wounding more than a dozen, Associated Press reported.

According to the Daily Mail, the attack started at dawn with a suicide car bomber hitting the main gate of the plant in the town of Taji, about 20 km north of Baghdad. Then several suicide bombers and militants broke into the plant and clashed with the security forces, an official said, adding that 25 troops were wounded.

In an statement, Iraq’s Deputy Oil Minister, Hamid Younis, said firefighters managed to control and extinguish a fire caused by the explosions.

Islamic Stated terrorists still control significant areas in northern and western Iraq, including the second-largest city of Mosul. It has declared an Islamic caliphate on the territory it holds in Iraq and Syria. Moreover, the group has recently increased its attacks far from the front lines in a campaign that Iraqi officials say is an attempt to distract from their recent battlefield losses.
