Air strikes targeting positions belonging to regime forces and Iran-backed militias in eastern Syria on Saturday night killed six fighters, the Britain-based Syrian Observatory for Human Rights said, according to AFP.

Four Syrian nationals were among those killed in the raids on the al-Abbas village near the border with Iraq, according to the organization.

It was not immediately clear if they were soldiers with the Syrian army.

The Observatory did not confirm who was behind the attack but said Israel was "likely responsible".

Earlier this week, the Observatory said that seven fighters, including two Syrian soldiers, were killed in air strikes attributed to Israel.

"Five pro-Iranian fighters were killed in a strike on a military center belonging to pro-Tehran militias" on the Sokhna-Deir Ezzor road in eastern Syria, Observatory chief Rami Abdel Rahman said, according to AFP.

He said many others were injured, with several in critical condition.

Two air force soldiers were killed in another raid on a telecommunications center in the southern Sweida province, he said.

Syrian media also confirmed the raids.

Israel does not comment on reports that it is behind air strikes in Syria.

There have been a series of air strikes attributed to Israel in Syria in recent months. Those air strikes have targeted the pro-Iranian militia and the Hezbollah organization as well as weapons convoys intended for Hezbollah.
