Turkish drones' destruction of Syrian regime air defence systems is "unprecedented", Charles Lister; a senior fellow and director of the Countering Terrorism and Extremism Program at the Middle East Institute said.
He added that only Israel has publicly done that.
Bloomberg quoted a senior Turkish official as saying that combat drones are a military innovation that demonstrated Ankara's technological bravery on the battlefield.
He added that revenge for the killing of 33 Turkish soldiers last week by Syrian regime forces includes the use of an unprecedented number of drones in coordinated action.
"This is the first time that a country has dominated airspace over this large area using drone squadrons," he said.
