Unknown warplanes attacked Iran-backed fighters in eastern Syria near the Iraqi border, killing several of the Iraqi militiamen, Syrian opposition activists said Sunday.
The strikes late Saturday targeted a base near the border town of Boukamal, killing seven fighters, according to the Britain-based Syrian Observatory for Human Rights, an opposition war monitor.
Omar Abu Laila, a Europe-based activist from Syria's eastern Deir el-Zour province, confirmed a strike hit Iran-backed Iraqi fighters in the area but had no exact word on casualties. The strikes came days after reinforcements were brought into the area from Iraq, the Observatory and Abu Laila said.
