Russian and Syrian Air Forces have reportedly carried out several coordinated air strikes on ISIL near a strategic military airbase in the northeastern province of Raqqa, west of the de facto capital of the self-proclaimed caliphate.

Syrian and Russian warplanes conducted a spate of coordinated air strikes against ISIL (Arabic acronym for Daesh) near Tabqa Air Base which resulted in the destruction of many of the terrorists’ military and logistics vehicles, according to the Iranian news agency FARS.

The attacks have impaired ISIL’s ability to supply its forces near the recently-liberated city of Palmyra with arms, medical equipment and food, FARS reported.

The airstrikes came shortly after sources said that scores of ISIL terrorists had been killed and many more wounded after the pro-government battalions of Raqqa province's tribal forces clashed with the terrorists in the area.

"The tribal forces and the Syrian Army have advanced against the ISIL terrorists in Qabaqeb and al-Tim oil well and are pushing towards the city of Raqqa," the sources said.

Meanwhile, fighting has erupted between a militant group and ISIL near Damascus, where Jaysh al-Islam (the Brigade of Islam) stormed ISIL positions to the northeast of the capital, according to the sources, which cited a heavy death toll from the fighting.
