Iranian media say a fire broke out at a bitumen storage facility in southern Iran, killing three workers.

Wednesday's report by the semi-official ILNA news agency says two other workers were injured in the fire. It says the firefighters are trying to put out the blaze at the facility in the port city of Bandar Abbas. No other details were immediately available.

Bandar Abbas is about 1,200 kilometers, or 750 miles, south of the capital, Tehran.

Iran's aging oil plants and related facilities, hard hit by years of Western sanctions, see occasional accidents, including fires.

In October, a fire at an oil rig in southern Iran killed four workers just days after an oil refinery fire killed seven.
