Iraq's Oil Ministry has resumed work at a natural gas plant north of Baghdad, two days after a coordinated dawn assault by Islamic State militants left at least 14 dead.

Deputy Minister Hamid Younis says work at the plant's three production lines returned "to normal levels" on Tuesday in Taji. The town is about 20 kilometers (12 miles) north of Baghdad.

Younis says the plant was back to full capacity of producing 30,000 cooking gas cylinders a day. He says Sunday's attack only damaged two gas storages and a few pipelines.

In the attack, a suicide car bomber hit the facility's main gate, followed by other suicide bombers and militants who broke into the plant and clashed with security forces.

IS-claimed attacks have killed more than 140 since last week.
