One of the world's most volatile regions was roiled further Tuesday when Turkey shot down a Russian warplane near the Turkish-Syrian border. Turkey said it hit the plane after it violated Turkey's airspace and ignored 10 warnings.
One of the two pilots was killed in the air by fire from the ground, the fate of the second pilot wasn't disclosed, and foreign sources states.
Turkey and Russia exchanged bellicose language after the downing of the plane, raising fears in the international community that the Syrian conflict could spiral into something wider.
The Russian plane was dealt with because it "did not answer our warning," Turkish President Recep Tayyip Erdogan said Tuesday.
ISIS isn't present at that border area, but Turkmen were there, Erdogan said. Anyone who bombs that area attacks "our brothers and sisters -- Turkmen," Erdogan said in Ankara. Turkmen are a Turkic-speaking, traditionally nomadic people who live primarily in Central Asia, but a small minority of them can be found in the Middle East, primarily in northern Iraq, Iran and Turkey.
