Five Iran fighters were killed by unidentified warplanes in Syria’s eastern province of Deir Ezzor near the Iraqi border, a Britain-based war monitor said on Sunday.
The strikes late Saturday targeted “positions of Iranian forces and allied militias” on the edge of the town of Albukamal, the Syrian Observatory for Human Rights said.
“Five non-Syrian fighters were killed,” Observatory chief Rami Abdel Rahman told AFP, without being able to provide their nationalities.
Regime troops, Iranian forces and allied Iran-backed fighters, including from Iraq, are present in the area on the western banks of the Euphrates River, he said.
According to the Observatory, 10 Iraqi fighters were killed in September in airstrikes of unknown origin in the same area.
At the start of that month, air raids killed 18 pro-Iran fighters, the monitor reported.
In June 2018, strikes near the Iraqi border killed 55 pro-regime forces, mostly Syrians and Iraqis, the Observatory said.
An American official said at the time that Israel was responsible, but the Jewish state declined to comment.
