The head of the International Energy Agency (IEA) said it could take about two years for the Middle East to recover energy output lost during the war on Iran, Al Jazeera reports.

Fatih Birol told Switzerland’s Neue Zuercher Zeitung newspaper that recovery times would differ across the region, with some countries taking longer than others.

“In Iraq, for example, it will take much longer than in Saudi Arabia,” Birol said.
