U.S. officials have said they believe air strikes on dozens of Iranian-linked sites in Syria and Iraq late on February 2 in retaliation for the killing of three U.S. troops in northwest Jordan were successful and warned more strikes will follow, as Baghdad expressed anger and concerns persisted of widening conflict in the region.
U.S. President Biden had warned of imminent action after a drone attack at a U.S. base in Jordan killed three U.S. service members on January 28.
Washington blamed Iran and its supply of weapons to militia groups in the region.
Reports said the U.S. strikes had hit seven locations, four in Syria and three in Iraq.
“Our response began today. It will continue at times and places of our choosing,” U.S. President Joe Biden said in a statement released shortly after the attacks that "our response began today," adding, "It will continue at times and places of our choosing."
“The United States does not seek conflict in the Middle East or anywhere else in the world. But let all those who might seek to do us harm know this: If you harm an American, we will respond,” he added.
General Yehia Rasool, a spokesman for Iraqi Prime Minister Shia al-Sudani accused the United States of a "violation" of Iraqi sovereignty with potentially "disastrous consequences for the security and stability of Iraq and the region."
After a previous U.S. air strike in Baghdad, Sudani asked for the 2,000 or so U.S. troops in Iraq to be withdrawn -- a sensitive bilateral topic.
U.S. National Security Council spokesman John Kirby said the United States "did inform the Iraqi government prior to the strikes" but did not provide details. He said the attacks lasted about 30 minutes and included B-1 bombers that had flown from the United States.
Kirby said defense officials would be able to further assess the strikes' impact on February 3.
The U.K.-based Syrian Observatory for Human Rights war monitor, which has extensive contacts inside Syria, said at least 18 pro-Iran fighters had been killed in a strike near Al-Mayadeen in Syria.
U.S. Central Command earlier confirmed the strikes, saying its forces "conducted air strikes in Iraq and Syria against Iran’s Islamic Revolutionary Guards Corps (IRGC) Quds Force and affiliated militia groups."
"U.S. military forces struck more than 85 targets, with numerous aircraft to include long-range bombers flown from United States," it said, adding that it had struck "command and control operations, centers, intelligence centers, rockets, and missiles, and unmanned aerial vehicle storages, and logistics and munition supply chain facilities of militia groups and their IRGC sponsors who facilitated attacks against U.S. and Coalition forces."
Syrian state media said there had been a number of casualties in several sites in Syria's desert areas along the border with Iraq.
U.S. officials have said that the deadly January 28 attack in Jordan carried the "footprints" of Tehran-sponsored Kataib Hizballah militia in Iraq and vowed to hold those responsible to account at a time and place of Washington’s choosing, most likely in Syria or Iraq.
On January 31, Kataib Hizballah extremists in Iraq announced a "suspension" of operations against U.S. forces. The group said the pause was meant to prevent "embarrassing" the Iraqi government and hinted that the drone attack had been linked to the U.S. support of Israel in the war in Gaza.
Biden has been under pressure from opposition Republicans to take a harder line against Iran following the Jordan attack, but said earlier this week that "I don't think we need a wider war in the Middle East. That's not what I'm looking for."
Iranian President Ebrahim Raisi has said Tehran "will not start any war, but if anyone wants to bully us, they will receive a strong response."
Biden on February 2 witnessed the return to the United States of the remains of the three American soldiers killed in Jordan at a service at the Dover Air Force Base, Delaware.
The clashes between U.S. forces and Iran-backed militia have come against the background of an intense four-month military campaign in Gaza Strip against the U.S.- and EU-designated terrorist group Hamas after a Hamas attack killed at least 1,200 people in Israel, most of them civilians.
Iran-backed Huthi rebels in Yemen have also waged attacks on international shipping in the region in what they call an effort to target Israeli vessels and demonstrate support for Palestinians.
U.S. Secretary of State Antony Blinken is traveling to his fifth round of crisis talks in the region from February 3-8, with visits reportedly planned to Saudi Arabia, Egypt, Qatar, Israel, and the West Bank in an effort to promote a release of hostages taken by Hamas in its brutal October 7 raids.
