Militants attacked a state-run natural gas plant outside the Iraqi capital, killing at least 11 people, officials said.
A police officer said Sunday’s assault started at dawn with a suicide car bomber hitting the main gate of the plant in the town of Taji, about 20 kilometers (12 miles) north of Baghdad. Several suicide bombers and militants then broke into the plant and clashed with security forces.
Fifteen other troops were also wounded in the attack, he added.
A medical official confirmed the casualty figures. Both officials spoke on condition of anonymity as they were not authorized to release information.
The Islamic State group has claimed responsibility for the attack.
The group recently increased their attacks far from the front lines in a campaign that Iraqi officials say is an attempt to distract from their recent battlefield losses.
