Early on July 4, several explosions were heard over the Turkish-occupied town of Azaz and the town of Taked in the northern and western countryside of Aleppo.
Several Opposition sources reported that the explosions had been caused by air-to-air missiles launched by warplanes of the Russian Aerospace Forces. Syrian observers confirmed that a number of Russian warplanes were in the air at the time.
Some sources claimed that the Russian warplanes had launched the missiles as a part of live fire exercises. Others, however, suggested that the missiles were launched at hostile unmanned aerial vehicles (UAVs).
Over the past few months, several similar explosions were reported over the North-Western region of Greater Idlib, which is occupied by terrorist groups.
Turkish-backed militants in northern Aleppo and terrorist groups in Greater Idlib are both known for using armed UAVs in attacks on Syrian and Russian forces. The most recent UAV attack took place on June 22.
The Ministry of Defense of Russia has not yet released any official statement on the matter. This leaves the door open for all possible suggestions.
