The pilots of a downed Russian aircraft did not respond to Turkish military warnings, a spokesman for the U.S.-led anti-Daesh coalition said Tuesday, SIA informs citing the Anadolu Agency.
Col. Steve Warren said coalition headquarters heard the incident on radar and confirmed Turkey’s military claim regarding the lack of response from the Russian pilots. The pilots were warned 10 times in 5 minutes, according to the Turkish Armed Forces.
Warren described the downing of the aircraft as "an incident between the Russian and the Turkish governments” and not one involving the coalition.
International norms prohibits an alien aircraft from flying over another state's airspace, he said.
"International norms are clear and well known by all players so there is no reason for an aircraft to fly over an area it shouldn't," Warren said.
