US ‘concerned’ that drones used in attacks on Russian bases in Syria available in ‘open market’

The Kheimim Airbase and the maritime logistics base in the city of Tartus came under a sophisticated attack Saturday, with terrorists for the first time using state-of-the-art drone technology to target the facilities, the Russian Defense Ministry reported Monday.

The Pentagon said it is “concerned” about weapons falling into terrorists’ hands after Moscow said the drones used in the attacks on Russian bases in Syria could have only been supplied by a “technologically advanced state.”
