Defense Secretary Lloyd Austin said in a statement that these latest strikes had been carried out in eastern Syria on facilities used by Iran’s Islamic Revolutionary Guard Corps and groups affiliated with it. They hit a training facility near the city of Abu Kamal and a safe house near Mayadin, he said.
President Biden directed the operation, Austin said, “to make clear that the United States will defend itself, its personnel, and its interests.”
A senior U.S. defense official, speaking on the condition of anonymity to discuss the operation, said the strikes were carried out by American fighter aircraft late Sunday. The training facility in Abu Kamal also was used to store weapons, this person said, noting that secondary explosions were observed after the strikes.
The safe house had functioned as a headquarters for groups affiliated with the IRGC, the senior defense official said. Militia personnel were present when the strikes occurred there, and the Pentagon assesses that some were killed, the official added. The fatalities were first reported by Fox News.
“We continue to message to Iran that we hold them accountable for these [attacks on U.S. personnel], and that their leaders must take action to constrain the activities of the groups Iran directs, trains, and equips,” the official said. “We will not hesitate to take further measures to protect our people, if necessary.”
The operation followed similar actions targeting facilities in Syria that U.S. officials said were linked to Iran, on Oct. 26 and again on Nov. 8. As of late last week, at least 46 attacks against U.S. troops had been documented since the middle of October, with dozens of American personnel sustaining what U.S. officials have characterized as minor injuries. The Pentagon said Thursday that, after the Nov. 8 strikes, U.S. personnel had come under attack three more times in Syria and once more in Iraq.
About 2,500 U.S. forces are based in Iraq and 900 in Syria as part of an enduring mission to prevent a resurgence of the Islamic State group. For years, those personnel have periodically come under fire from one-way attack drones and rockets, but such incidents have spiked in the weeks since Israel declared war on the militant group Hamas following its cross-border attack in Israel on Oct. 7. Hamas and other militant groups in the region receive weapons and training from Iran, raising concerns that the war in Gaza could widen.
Austin, speaking to reporters in India on Friday, said that the protection of U.S. troops is of the “utmost importance, and we’re going to continue to do everything that we need to do to protect our people.”
“We won’t ever project or predict or advertise when we’re going to conduct a strike, but we will — rest assured that we will strike at a time and place of our choosing,” he said. “These attacks against our people must stop, you know?”
