The United States carried out retaliatory airstrikes on Friday in Iraq and Syria against more than 85 targets linked to Iran’s Revolutionary Guard (IRGC) and the militias it backs, the US military said.

The retaliatory strikes – which lasted 30 minutes and were successful, according to the White House – came in response to a drone strike by Iran-backed militants on a US military outpost in Jordan on Sunday, which killed three US service members and wounded more than 40 others.

“US military forces struck more than 85 targets, with numerous aircraft to include long-range bombers flown from United States. The airstrikes employed more than 125 precision munitions,” the US Central Command said in a statement.

“The facilities that were struck included 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,” it added.

Defense Secretary Lloyd Austin said in a statement that the strikes are “the start of our response.”

US President Joe Biden said in a statement that the US military response “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,” Biden said.
