Iran claimed responsibility Sunday for a missile barrage that struck near a sprawling U.S. consulate complex in the northern Iraqi city of Irbil, saying it was retaliation for an Israeli strike in Syria that killed two members of its Revolutionary Guard earlier this week. No injuries were reported in Sunday's attack on the city of Irbil, which marked a significant escalation between the U.S. and Iran. Hostility between the longtime foes has often played out in Iraq, whose government is allied with both countries. Iran’s powerful Revolutionary Guard said on its website that it attacked what it described as an Israeli spy center in Irbil. It did not elaborate, but in a statement said Israel had been on the offensive, citing the recent strike that killed two members of the Revolutionary Guard. The semi-official Tasnim news agency quoted an unnamed source as saying Iran fired 10 Fateh missiles, including several Fateh-110 missiles, which have a range of about 300 kilometers (186 miles). The source said the attack resulted in multiple casualties and said the main target for the missiles was the "Zionist base, which is far from the American military base.” Read: Iran launches rocket into space amid Vienna nuclear talks An Iraqi official in Baghdad initially said several missiles had hit the U.S. consulate in Irbil, the intended target of the attack. Later, Lawk Ghafari, the head of Kurdistan’s foreign media office, said none of the missiles had struck the U.S. facility but that residential areas around the compound had been hit. In a Twitter post, he said the lack of reaction from the international community to repeated attacks by Iran on Kurdistan “is of great concern” and was encouraging future attacks by Tehran. A U.S. defense official said the strike was launched from neighboring Iran, and that it was still uncertain how many missiles were fired and where they landed. A second U.S. official said there was no damage at any U.S. government facility and that there was no indication the target was the consulate building, which is new and unoccupied. Neither the Iraqi official nor the U.S. officials were authorized to discuss the event with the media and spoke to The Associated Press on condition of anonymity. Satellite broadcast channel Kurdistan24, which is located near the U.S. consulate, went on air from their studio shortly after the attack, showing shattered glass and debris on their studio floor. The attack came several days after Iran said it would retaliate for an Israeli strike near Damascus, Syria, that killed two members of its Revolutionary Guard. On Sunday, Iran’s state-run IRNA news agency quoted Iraqi media acknowledging the attacks in Irbil, without saying where they originated. The missile barrage coincided with regional tensions. Negotiations in Vienna over Tehran’s tattered nuclear deal hit a “pause” over Russian demands about sanctions targeting Moscow for its war on Ukraine. Meanwhile, Iran suspended its secret Baghdad-brokered talks aimed at defusing yearslong tensions with regional rival Saudi Arabia, after Saudi Arabia carried out its largest known mass execution in its modern history with over three dozens Shiites killed. The Iraqi security officials said there were no casualties from the Irbil attack, which they said occurred after midnight and caused material damage in the area. They spoke on condition of anonymity in line with regulations. One of the Iraqi officials said the ballistic missiles were fired from Iran, without elaborating. He said the Iranian-made Fateh-110 missiles likely were fired in retaliation for the two Revolutionary Guards killed in Syria. The U.S. ambassador to Iraq, Mathew Tueller, said the U.S. condemns the criminal attack on civilian targets in Irbil. “Iranian regime elements have claimed responsibility for this attack and must be held accountable for this flagrant violation of Iraqi sovereignty,” he said in a statement posted by the U.S. consulate in Irbil. U.S. forces stationed at Irbil’s airport compound have come under fire from rocket and drone attacks in the past, with U.S. officials blaming Iran-backed groups. The top U.S. commander for the Middle East has repeatedly warned about the increasing threats of attacks from Iran and Iranian-backed militias on troops and allies in Iraq and Syria. In an interview with The Associated Press in December, Marine Gen. Frank McKenzie said that while U.S. forces in Iraq have shifted to a non-combat role, Iran and its proxies still want all American troops to leave the country. As a result, he said, that may trigger more attacks.’ The Biden administration decided last July to end the U.S. combat mission in Iraq by Dec. 31, and U.S. forces gradually moved to an advisory role last year. The troops will still provide air support and other military aid for Iraq’s fight against the Islamic State. The U.S. presence in Iraq has long been a flash point for Tehran, but tensions spiked after a January 2020 U.S. drone strike near the Baghdad airport killed a top Iranian general. In retaliation, Iran launched a barrage of missiles at al-Asad airbase, where U.S. troops were stationed. More than 100 service members suffered traumatic brain injuries in the blasts. More recently, Iranian proxies are believed responsible for an assassination attempt late last year on Iraq’s Prime Minister Mustafa al-Kadhimi.

No U.S. personnel were killed or injured in the attack. Al-Kadhimi tweeted: “The aggression which targeted the dear city of Irbil and spread fear amongst its inhabitants is an attack on the security of our people.” Masrour Barzani, prime minister of the semi-autonomous Kurdish-controlled region, condemned the attack. In a Facebook post, he said Irbil “will not bow to the cowards who carried out the terrorist attack.”
