After an incident in the airspace over the Aegean, Turkish President Recep Tayyip Erdogan has threatened Greece with consequences. Athens will pay a “high price” if it continues to violate Turkish airspace and “harass” Turkish fighter jets over the Aegean Sea, Erdogan said at a rally in the Black Sea city of Samsun on Saturday.

Last weekend, Ankara accused Greece of “hostile action” against Turkish fighter jets. The Greek army used an air defense system from Russia to track the Turkish fighter jets by radar, it said. In his speech, Erdogan accused Greece of trying to threaten Turkey with the “S-300” missile system.

“Hey Greece, look at history. If you go further, you will pay a high price,” Erdogan said. Greece and Turkey are allies in NATO, but their relations have been marked by great tension for decades. Above all, competing territorial claims in the Aegean are causing disputes.

Both sides regularly accuse each other of violating borders and treaties. There are also almost daily reconnaissance flights from both countries, especially around the Greek islands near the Turkish coast.
