Iran’s Islamic Revolutionary Guard Corps claims to have launched multiple ballistic missiles at Israeli “spy headquarters” and “anti-Iranian terrorist groups” in northern Iraq late Monday as tensions escalate in the Middle East.

The IRGC, which operates under Ayatollah Ali Khamenei, claimed credit for the attacks on what they identified as Mossad headquarters after a series of explosions were heard outside the city of Erbil in Iraqi Kurdistan.

No U.S. facilities were struck in the attacks, two U.S. officials told Reuters.

“In response to the recent terrorist crimes of the enemies of Islamic Republic of Iran, the spy headquarters and the gathering of anti-Iranian terrorist groups in parts of the region were targeted by the IRGC’s ballistic missiles in the middle of the night,” the IRGC said in a statement reported by Iranian state media.

The military act is monumental, as this is the first time since the Hamas attack of October 7 that the Iranian military has directly struck enemy targets. Previous attacks have been carried out by Iran’s terror proxies, including Hezbollah and Houthi militants.

At least four civilians were killed and six injured in the attack, Kurdistan government officials announced.

Prominent Kurdish businessman Peshraw Dizayee and several members of his family were killed when one of the missiles struck their home, Iraqi security officials said.

The attack comes hours after the Iran-backed Houthis hit a U.S.-owned and operated cargo ship in the Red Sea earlier Monday.
