"We confirm that Ambassador Andrei Karlov had a meeting in the Turkish Foreign Ministry. We do not comment on the content of his talks with his colleagues from the Turkish Foreign Ministry," the embassy's spokesperson, Igor Mityakov, told RIA Novosti.
The alleged incident involving a Su-34 fighter bomber took place on Friday, the Turkish Foreign Ministry said in a statement adding that the plane had been warned by Turkish air radar units.
"At the meeting we strongly protested and condemned this violation and reiterated, once again, aforementioned concerns as to the gravity of such violations," the Turkish ministry said.
On November 24, a Turkish F-16 fighter shot down a Russian Su-24 bomber with two pilots on board over Syria. Ankara claimed it had downed the Russian warplane as it had allegedly violated Turkish airspace. Both the Russian General Staff and the Syrian Air Defense Command have confirmed that the Russian jet never crossed into Turkish airspace.
In response to Ankara's "stab in the back," as the incident has been described by Russian President Vladimir Putin, Moscow imposed a number of economic measures on Turkey.
