Turkey is facing the wrath of Russian President Vladimir Putin after shooting down a Russian fighter near the Syrian border Tuesday morning.
Turkish officials claim it only took the action after issuing several warnings to the Russian warplane reportedly violating Turkish airspace.
Russia is of a different mind.
But Russia's state-run Sputnik news agency said that, "According to preliminary reports, the plane was gunned down from the ground."
Russian officials denied that the plane had violated Turkish airspace. Both pilots ejected from the plane, but their fate is unknown, Sputnik reported.
Putin issued a warning in response to the incident. The downing, he said, is a "stab in the back that will have serious consequences for Russia's relationship with Turkey."
The pilots ejected from the plane before it crashed, but still no word on whether they survived, CNN reports.
NATO is expected to hold an emergency meeting in Brussels at 11 a.m. ET.
