By “suspected” Israeli airstrikes in eastern Syria on Monday, ten pro-Iranian fighters, most of them Iraqis, were killed, according to a human rights organization.
Attacks on militant positions south of the city of Albu Kamal have left eight Iraqi and two Syrian fighters dead.
Ammunition depots and vehicles have also been destroyed, according to the Syrian Observatory for Human Rights.
Israel does not claim to carry out systematic attacks in Syria.
But since 2011, the Jewish state has launched hundreds of raids against the forces of the Syrian regime, as well as those of its allies, Iran and Lebanese Hezbollah.
On September 3, 16 more pro-Iranian fighters were killed in “likely” Israeli attacks in Deir Ezzor, the observatory said.
