Turkey's foreign ministry said on Saturday that a Russian SU-34 jet had violated Turkish airspace despite radar warnings, Reuters reported.
Russia's ambassador to Turkey was summoned amid ongoing bitterness between Ankara and Moscow. The Turkish foreign ministry said in a statement that the violation was a clear sign that Russia wished to continue escalating the issues between the two countries.
"We are making a clear call to the Russian Federation not to violate Turkish airspace, which is also NATO airspace," the statement said. "We are emphasizing once again that the unwanted consequences of such irresponsible behavior will belong fully to the Russian Federation."
In November, Turkey downed a Russian warplane in a similar dispute over whether Russia had violated Turkish airspace. Russia has since imposed economic sanctions on Turkey, targeting its tourism industry and exports.
