The Russian Defense Ministry confirmed that Syrian army positions were attacked by two F-16 fighter jets and two A-10 ground attack aircraft of the US-led coalition.

"Today at 17:00-17:50 Moscow time, international anti-Daesh coalition (two F-16 and two A-10 jets) carried out four strikes on Syrian government forces' units encirled by Daesh near Deir ez-Zor airport. The coalition's aircraft entered Syrian airspace from the side of the Iraqi border," Maj. Gen. Igor Konashenkov said.

Earlier in the day, the General Command of the Syrian army accused the US-led coalition of bombing the Syrian army's positions in Deir ez-Zor.

As a result of the attack, 80 Syrian soldiers were killed and some 100 others were injured, according to information received from the Syrian command in Deir ez-Zor, he said.

The Russian Defense Ministry said that Daesh terrorists launched an offensive soon after the US-led coalition aircraft attacked the Syrian government forces.

"If this airstrike was carried out due to an error in the coordinates of the targetm it is a direct consequence of US side's unwillingless to coordinate its actions against terrorist groups with Russia," the Russian Defense Ministry spokesman emphasized.

Konashenkov said that fighting with terrorists has been taking place near the Deir ez-Zor airport.
