from Fars News:
Russia’s Defense Ministry confirmed a report by the Syrian state news agency that an ISIL offensive began right after Syrian Army positions were hit from the air.
The actions of the coalition “clearly paved the way for ISIL terrorists to attack the position and take control of it,” the agency said citing the General Command of the Army and Armed Forces.
The General Command called the bombing a “serious and blatant aggression” against Syrian forces, and said it was “conclusive evidence” that the US and its allies support ISIL terrorist group.
A day later on Sunday, a military source disclosed that the ISIL launched attacks on the Syrian army positions in Deir Ezzur only 7 minutes after the US-led coalition’s airstrikes.
The military source reiterated that the air and ground assault were highly coordinated.
The source said after the coalition’s pounding of the Syrian army near Deir Ezzur airbase, the ISIL could take full control of al-Thardah mountain and then Deir Ezzur military base, adding that the army and national defense forces deployed near the airbase immediately won it back from the terrorists by launching a counterattack.
The source said the simultaneous raid of the ISIL terrorists immediately after the coalition airstrikes is the best evidence of the high coordination done between the US and the terrorists.
