Breaking:A Russian warplane has been shot down by Turkey on the Syrian border

According to reports out Tuesday morning, a military jet has been shot down on the Turkish-Syrian border. 

According to Reuters, the Turkish military says that it shot down a Russian jet that violated the country's airspace and that the aircraft did not respond to repeated warnings. 

Sputnik News, a Russian state-owned media service, received confirmation from the defence ministry in Moscow that the Su-24 jet belonged to Russia.

Turkey says the jet was shot down by Turkish F-16 fighter aircraft after violating Turkish airspace, while the Russian defence ministry has suggested that the plane was shot from the ground while it was in Syrian airspace.

The discrepancies between the Turkish and Russian reports of how the plane was shot down could not immediately be explained.

In a press conference, Russian President Vladimir Putin called the act a "stab in the back by the associates of terrorism," and said that the jet had been shot down with surface-to-air missiles.

He added: "Today's tragic event will have serious consequences for Russian-Turkish relations."

The jet was carrying two people, both of whom reportedly ejected. According to CNN in Turkey, one of the pilots has been captured by Turkmen forces, rebels in Syria with close ethnic and historical links to Turkey.

According to the Associated Press, the rebel group that captured the surviving pilot says the other was dead upon landing.

According to Agence France-Presse, NATO has called an "extraordinary meeting" after the incident. Turkey is part of NATO, whose member nations are bound by the treaty to defend one another from aggression. 

A US official told The Daily Beast that the coalition had received no warning from Turkey before it downed the Russian plane. "They just did it," the official said.

Turkey has reportedly summoned a Russian envoy to Ankara to discuss the incident.

The Turkish military published a radar map demonstrating the reported flight path of the jet that it shot down, which Ankara is using as proof that the pilots violated the country's airspace:

Russian military forces are working in support of President Bashar Assad, and their presence has grown considerably since September, when airstrikes began.

According to Reuters, the Syrian Observatory for Human Rights said the jet crashed in Latakia province, a part of northwestern Syria bordering Turkey. There was reportedly bombing in the area earlier, and fighting between rebel groups and the government over the last week.

On Friday, Turkey summoned Russian ambassador Andrey G. Karlov and called for animmediate end to Russia's military operation close to the Turkish border. Turkey accused Russia of bombing villages in northern Syria inhabited by Syrian Turkmens, who are Syrians of Turkish descent. 

“It was stressed that the Russian side’s actions were not a fight against terror, but they bombed civilian Turkmen villages and this could lead to serious consequences,” said a statement released by the Turkish Foreign Ministry.

According to Turkish media, there are now Russian helicopters searching the area that the jet came down in:
