NATO warns Russia over 'airspace violation'

NATO has called on Russia to act responsibly after Turkey summoned the Russian ambassador to protest what it claimed was a violation of its airspace by a Russian warplane. "A Russian combat aircraft violated Turkish airspace yesterday, despite repeated warnings by the Turkish authorities," said NATO Secretary General Jens Stoltenberg in a statement on Saturday.

"Previous incidents have shown how dangerous such behavior is," he said.

He called on Russia to act responsibly and to fully respect NATO airspace. Turkey has been a member of the alliance since 1952.
