BEIRUT, March 25 (Reuters) – The death toll in U.S. air strikes on pro-Iran installations in eastern Syria has risen to 19 fighters, a Syrian war monitor said on Saturday, in one of the deadliest exchanges between the U.S. and Iran-aligned forces in years.
The U.S. carried out strikes in eastern Syria in response to a drone attack on Thursday that left one American contractor dead, and another one wounded along with five U.S. troops. Washington said the attack was of Iranian origin.
The retaliatory strikes by the U.S. on what it said were facilities in Syria used by groups affiliated to Iran‘s Revolutionary Guard Corps left a total of 19 dead, according to the U.K.-based Syrian Observatory for Human Rights.
The war monitor said air raids killed three Syrian troops, 11 Syrian fighters in pro-government militias and five non-Syrian fighters who were aligned with the government.
The monitor’s head Rami Abdel Rahman could not specify the nationalities of the foreigners. Reuters was unable to independently confirm the toll.
The initial exchange prompted a string of tit-for-tat strikes. Another U.S. service member was wounded, according to officials, and local sources said suspected U.S. rocket fire hit more locations in eastern Syria.
President Joe Biden on Friday warned Iran that the United States would “act forcefully” to protect Americans.
Iran has been a major backer of President Bashar al-Assad during Syria’s 12-year conflict.
Iran‘s proxy militias, including Lebanese group Hezbollah and pro-Tehran Iraqi groups, hold sway in swathes of eastern, southern and northern Syria and in suburbs around the capital.
Tehran’s growing entrenchment in Syria has drawn regular Israeli air strikes but American aerial raids are more rare. The U.S. has been raising the alarm about Iran‘s drone program.
