Tensions are running high on the Turkey-Syria border following the shooting down of a Syrian warplane by Turkish forces at the weekend, the Turkish army said Tuesday. "During one mission... five F-16 jets were followed by anti-air missiles... deployed by Syria, which were locked on our aircraft for 10 minutes, 53 seconds," it said in a statement. Local media also reported that Turkey has deployed specialist elite units on the border. Damascus accused Ankara of "flagrant aggression" after the plane was shot down and crashed on Syrian territory on Sunday as Syrian loyalists and rebels battled for control of a frontier crossing.
