The attack resulted in casualties and destroyed Syrian army's equipment and "clearly paved the way" for Daesh terrorist group to advance and gain control over the position, the General Command said as quoted by SANA.
Damascus called the US-led coalition's alleged attack a "serious and blatant aggression" against Syria and Syrian government army.
The Syrian military added that it "constitutes conclusive evidence that the United States and its allies support ISIS [Daesh] and other terrorist organizations, stressing that this act reveals the falseness of their claims of fighting terrorism."
The news comes amid a ceasefire in Syria agreed by Russian Foreign Minister Sergey Lavrov and US Secretary of State John Kerry on September 9. The ceasefire stipulated by the US-Russia agreement came into force on September 12.
