Biggest UAE Refinery Halts as Precaution After Drone Attack

The United Arab Emirates halted its huge Ruwais oil refinery, one of the world’s largest, as a precautionary measure after a drone strike caused a fire in the industrial area in which it’s located, according to people familiar with the matter.

Abu Dhabi National Oil Co. was assessing damage at the plant, the people said, asking not to be named because the matter is not yet public. The refinery can process 922,000 barrels of oil a day.
