A warplane crashes in a mountainous area in northern Syria after being shot down by Turkish fighter jets near the Turkish-Syrian border yesterday. Turkey said its fighter jets shot down the Russian warplane, a Russian-made SU-24, after repeated warnings over air space violations, but Russia said it could prove the jet had not left Syrian air space. It was the first time a NATO member’s armed forces have downed a Russian or Soviet military aircraft since the 1950s, and Russian and Turkish stocks fell on fears of an escalation between the former Cold War enemies.
