“Yesterday, it made incursions into Iranian territory in the province of Azerbaijan, where it took over seven towns.” — i can’t find independent confirmation of this. Only a BBC tweet with a link to BBC Persian saying a pro IS satellite news in Iraq has claimed there have clashes between members of IS & Iranian revolurionary guard around Urmia. If true i think they’re entering iranian azarbaijan from Turkey.
Thought you might’ve heard or seen more info on this?
