The Department also warned that now any airborne targets, including aircraft and unmanned vehicles international coalition discovered to the West of the Euphrates river, "will be available for support" as air targets.
The defense Ministry also called the actions of the US in Syria military aggression.
A day earlier, the Syrian government announced that the international coalition forces led by the USA shot down a military aircraft of the Syrian air force. It is reported that the incident occurred near the town of es-Thawra in raqqa province.
Damascus claims that the aircraft was performing a combat mission against the extremist group "Islamic state" banned in several countries. The Syrian statement said that this will have dangerous consequences in the fight against terrorism.
In turn, the American military claimed that Syrian military aircraft dropped bombs near a group of rebels who are supported by America, and then was shot down by US air force aircraft.
