A power cut shut down operations at Iraq's largest oil refinery on Sunday, officials at the plant said, adding it was unclear when work would resume.
The plant in Baiji, 180 km (112 miles) north of Baghdad, refines around 275,000 barrels of crude oil per day into gasoline, diesel and other products for the domestic market. Officials said exports were not affected by the incident.
"This morning at 8:15 work at the refinery was stopped completely because of the shutdown of electricity," said a senior official at the refinery.
An engineer at the plant said it was unclear when operations would resume.
A power cut halted production at the Baiji refinery in January, closing it for two days. (Reuters)
