According to Ankara, the incident involving a Russian Su-34 took place Friday. Several warnings in Russian and in English were allegedly sent to the jet.
"We are making a clear call to the Russian Federation not to violate Turkish airspace, which is also NATO airspace," the Turkish Foreign Ministry said in a statement Saturday.
"We are emphasizing once again that the unwanted consequences of such irresponsible behavior will belong fully to the Russian Federation," it added.
The ministry also said it views the alleged violation as a clear sign that Russia is seeking to escalate the already existing tensions.
The Russian embassy in Ankara confirms the envoy has been summoned.
"We confirm that the ambassador, Andrey Karlov, has had a meeting in the Turkish Foreign Ministry," Igor Mityakov, the press secretary of the Russian embassy in Ankara, told RIA Novosti following Turkey's statement. He did not confirm the incident itself and provided no further comment.
In November, Turkey downed a Russian bomber, a Su-24, after it briefly violated the country's airspace. The plane went down in Syria with Moscow saying that it only spent 17 seconds over Turkish territory.
The incident provoked a deep political crisis between Ankara and Moscow. Turkey's President Recep Tayyip Erdogan has so far refused to apologize for the incident and blamed the downing of the Russian bomber on the pilots. One of the two pilots was killed in the incident.
Following the downing, Moscow introduced multiple sanctions against Ankara, banning agricultural trade with Turkey, reintroducing a visa regime and suspending most bilateral economic projects, including the Turkish Stream gas pipeline construction project.
Moscow has been carrying out an anti-terrorist operation in neighboring Syria since September 2015. Russia's Su-27 and Su-30 fighter jets, Su-34 and Su-24 tactical bombers and Su-25 attack aircrafts are taking part in airstrikes on Islamic State (IS, former ISIS, ISIL) and other Syrian terrorist groups.
The Turks dare not challenge the SU-34; they know well this is not a slow unprotected bomber like that they shot down in an act of cowardice.
