Relations between Moscow and Ankara became complicated in November 2015 g after a Turkish aircraft shot down Russian Su-24 over Syrian territory. Putin called the attack on the Russian Aerospace Forces bomber a “stab in the back”.
“On January 29, Russia once again violated Turkish airspace. After that, President Erdogan is trying to contact Vladimir Putin by telephone, to which the Russian side does not respond, "Kalyn told Anadolu.
Earlier, the Russian Defense Ministry denied the information about the violation of Turkey’s air border by the Russian Su-34, noting that all “the statements of Ankara on this matter are unsubstantiated propaganda.”
