Turkey has released an audio recording of what it claims are warnings given to a Russian warplane before it was shot down near the Syrian border.
According to the Turkish military, the Russian SU-24 attack aircraft was hailed 10 times before it was engaged and brought down on the Syria/Turkey border.
"Change your heading south," a voice says in English through heavy static in the clip.
The surviving Russian pilot, Captain Konstantin Murakhtin, insists that he did not receive a warning beforehand.
Captain Murakhtin was rescued and is currently at a Russian air base in Syria but his co-pilot was reportedly killed by militants on the ground.
Turkey has shown it is willing to take on Russia after downing a Russian fighter jet.
This incident will leave the American military profoundly alarmed that the Syrian conflict is now threatening to spiral out of all control.
