BREAKING NEWS: TURKEY JUST SHOT A RUSSIAN PLANE OUT OF THE SKY
According to reports, eyewitnesses saw a large explosion in Huraytan, northern Syria, while three fighter jets were hovering above.
One journalist tweeted that three Turkish planes were responding to "mysterious" lock-ons from Mig-29 jets, which are used by Putin's forces.
Daily Star Online has contacted the Turkish government and the Russian military but neither could be reached for comment.
It comes amid heightening tensions between Putin and the West just days after another Russian bomber violated Turkish airspace.
F-16 fighters were scrambled after a MIG-29 twin-engined jet locked radar on Turkish planes near the town of Yayladagi, in Hatay province close to the border with Syria.
Turkish jets then escorted the Soviet-era aircraft back into Syrian airspace.
The incursion followed nearly a week of Russia's devastating bombing campaign in Syria after President Vladimir Putin declared war on Islamic State (ISIS).
