This is an odd report. JPost picked up a report attributed to BBC, that Iranian authorities have called for an evacuation of Isfahan over pollution. The BBC news site doesn’t appear to have that item though.

The reports further indicate that the evacuation edict was not for pollution, but a possible problem at one of Iran’s nuclear facilities in the city that began back in November (according to other sources).

I haven’t seen confirmation of any of this anywhere else. The evacuation of a city with 1.5 million people would certainly register with folks in the intel community. It would certainly get more than a couple of minor writeups.
