US warplanes carried out a strike on an Iran-linked weapons storage facility in eastern Syria on Wednesday in response to attacks against American personnel, US Defense Secretary Lloyd Austin said.
It is the second time in roughly two weeks that the United States has targeted a location in Syria it said was tied to Iran, which supports an array of groups that Washington blames for a spike in attacks on its forces in the Middle East.
The United States is striving to deter Iran and its proxies from turning the Israel-Hamas fighting into a regional war, but the repeated attacks and strikes in response risk a conflict between Washington and Tehran.
"US military forces conducted a self-defense strike on a facility in eastern Syria used by Iran's Islamic Revolutionary Guard Corps (IRGC) and affiliated groups. This strike was conducted by two US F-15s against a weapons storage facility," Austin said in a statement.
"This precision self-defense strike is a response to a series of attacks against US personnel in Iraq and Syria by IRGC-Quds Force affiliates," Austin said, adding that the United States "is fully prepared to take further necessary measures to protect our people and our facilities."
The Syrian Observatory for Human Rights war monitor said the Wednesday strike killed nine people affiliated with Iran-backed groups in Syria -- a toll that could not be independently confirmed.
The US military also hit two facilities in Syria on October 26 that it said were used by the IRGC and affiliated groups, and assessed that those strikes did not cause casualties.
Like the most recent strike, Washington said the earlier two were in response to attacks on US personnel, who have been targeted more than 40 times with rockets and drones since October 17.
The surge in attacks on US troops is linked to the war between Israel and Hamas, which began when the militant group carried out a shock cross-border attack from Gaza on October 7 that Israeli officials say killed more than 1,400 people.
Israel's military responded with a relentless air, land and naval assault on Gaza that the territory's health ministry said has left more than 10,500 people dead.
