Iran’s Revolutionary Guards on Monday launched ballistic missiles at what it said was a spy base for Israel’s intelligence agency Mossad in northern Iraq, and at “anti-Iran terror groups” in Syria, in the latest escalation of hostilities that further risks spiraling into a wider regional conflict.

The strikes were condemned by the United States as “reckless” and imprecise.

Iranian forces said the midnight missile strike in Iraq destroyed “one of the main espionage headquarters” of Israel in Erbil, capital of the semi-autonomous Kurdistan region, in response to what they said were Israeli attacks that killed Iranian Revolutionary Guard commanders and members of the Iranian resistance front.
