An airstrike in eastern Syria on Sunday killed five non-Syrian fighters backed by Iran, a Britain-based war monitor said.
The strike targeted three military vehicles belonging to Iran-backed paramilitary fighters near the Iraqi border, the Syrian Observatory for Human Rights said.
The monitor did not say who was behind the attack near the border town of Albu Kamal.
But Observatory head Rami Abdul Rahman said that “Israel was likely responsible.”
Earlier, Sky News Arabia reported that unidentified aircraft carried out a pre-dawn bombing and also said that the targets were Tehran-linked forces.
