Iran's state media reported a fire in an engine oil refinery in northwestern region of the country early Sunday. The fire happened in an industrial region near the city of Azar Shahr.

Authorities say there have been no casualties, and only a firefighter has been injured. The incident coincided with a drone attack on an Iranian defense factory in the central city of Isfahan overnight. It's not clear if there are any links between the two incidents.
