Turkey said that radar used by Russian aircraft and its surface-to-air missile systems in Syria locked on to Turkish jets as the Russian air campaign intensifies against opposition targets.
The Turkish military said that eight Turkish F-16 fighters patrolling the Turkish Syrian border had been threatened by a Mig-29 and later by an anti-aircraft missile system. In both cases the threat consisted only of Russian use of radar for a limited period, but the Nato Secretary-General Jens Stoltenberg said that Russian actions were “very serious – even dangerous”. “It doesn’t look like an accident, and we’ve seen two of them over the weekend.”
