"During the day, 12 cases of violations of the deconfliction protocols of December 2019 were recorded, related to flights of unmanned aerial vehicles not coordinated with the Russian side by the so-called 'international anti-terrorist coalition' led by the United States," Gurinov told a briefing. He added that two F-16 fighter jets and a MC-12W reconnaissance jet had violated the airspace in the Al-Tanf area, through which international air routes pass.
