Ilya Kusa, a Ukrainian international affairs expert, has said that “there were lots of [drones] in the sky immediately after the rocket attacks” amid the US-Iranian tensions.
According to Kusa, the drones are small and difficult to notice and insisted it is difficult not to connect the plane crash with the US-Iran confrontation.
The aircraft, flight number PS752, took off at around 6.14am local time and reached 7,952ft before crashing to kill all 179 people on board.
Kusa added: “One must understand that this happened shortly after Iran’s missile attacks on US military facilities.
“Everyone was tense, expecting continued shelling.”
Honoured Russian military pilot Vladimir Popov said: “It could have been an unmanned reconnaissance aircraft, which are small in size and poorly visible on radars.
“A plane in a collision could get significant damage and even catch fire in the air.”
The experts said both Iranian and US drones were in the air at the time.
Though Ukrainian and Iranian authorities are insisting the crash was caused by engine failure, found black box and the Ukraine International Airlines have said there was nothing wrong with the plane.
