UPDATE: It looks as though Iran fired 5-6 ground-to-ground missiles from a base in Tabriz in retaliation for the deaths of two Iranian miltary leaders in Syria. The Israeli airforce reportedly killed the two last week. Sources in Iran are saying it was an Mossad (Israeli intelligence agency) site that was targeted. There are no reports of any casualties.
Video of what appears to be mulitple missiles hitting in the area of the US consulate in Erbil, Iraq (this is the northern Kurdish region) is hitting the wires.
At the moment, it is unclear who launched the missiles.
