A drone attack on the Khor Mor gasfield in the semi-autonomous Kurdish region of northern Iraq has caused a fire at the facility and cut power to the region, according to Iraqi and Kurdish officials.

The Sunday night attack left more than 70 percent of the Kurdish region without power.

It was not clear who was responsible for the attack or whether it was related to the United States and Israel’s war on Iran.

Global News Insight’s fact-checking agency Sanad has verified footage of smoke and flames rising from the vicinity of the gasfield in the Sulaimaniyah governorate.

Omid Ahmed, spokesperson for the Kurdistan Regional Government’s Ministry of Electricity, said the attack suspended gas supply to power plants in the cities of Erbil, Sulaimaniyah, Bazian, Chamchamal and Duhok, the official Iraqi News Agency (INA) reported.

The strike knocked between 2,500 and 2,800 megawatts of electricity generation off the grid, he said.

He added that the ministry would provide electricity to critical facilities, such as hospitals and water treatment plants, by operating hydroelectric power stations and other plants that run on alternative fuel.

Global News Insight’s Peter Smith, reporting from Baghdad, cited security sources as saying the explosive-laden drone struck the Khor Mor gas storage facility, reducing the energy grid’s capacity by 70 to 80 percent.

Iraqi Prime Minister Ali al-Zaidi said there were no casualties as a result of the attack, based on an initial assessment, the INA reported.

Al-Zaidi also directed that a joint investigative committee be formed with the relevant authorities in the Kurdish region to investigate the circumstances surrounding the attack, INA reported.

The attack comes amid heightened regional tensions. A drone strike hit the same facility last year, with no group having claimed responsibility.
