A Russian warplane goes down in Syria's Bayirbucak region, near the Turkish border, on November 24, 2015.

The Turkish military says it shot down the unidentified warplane, contending it repeatedly violated Turkish airspace.

Turkey's semi-official Anadolu Agency cites Turkish presidential sources in reporting that a Russian SU-24 was "hit within the framework of engagement rules."

The Anadolu Agency reported that a parachute was also seen leaving the jet before it crashed. The fate of the airman remains unclear.

The Turkish government is strongly opposed to the Syrian regime of Bashar al-Assad. Russia, however, has backed Assad, and has had warplanes active over Syria.

Heavy smoke has been seen in the area where the plane fell.
