The Islamic State group killed nine Iran-trained Syrian fighters in an attack on one of their positions in eastern Syria, a war monitor said according to syrianobserver.com.
The Britain-based Syrian Observatory for Human Rights said an IS sleeper cell carried out the dawn attack on the desert outpost outside the Euphrates Valley town of Al-Mayadeen.
Observatory head Rami Abdul Rahman said the fighters killed were Syrians led and trained by Iran’s elite Revolutionary Guards.
At least two IS fighters were killed in ensuing clashes.
Since March 2019, intermittent fighting has killed more than 1,000 government troops and allied Iran-backed militiamen, most of them in sparsely populated areas of the Syrian Desert, the Observatory says.
