Iranian officials on Wednesday ordered residents of Isfahan to evacuate the city, the BBC reported, sparking renewed concern a nearby uranium enrichment site is leaking radioactive material.
According to the report, the edict calls on Isfahan's one-and-a-half million people to leave the city because pollution has now reached emergency levels.
Iranian officials previously denied that a leak occurred at the facility, and accused the West of fabricating the story in order to create tumult in the region.
