Unhindered by NATO or the European Union, Turkish fighter jets violated Greek airspace again when two flew into Athens’ Flight Information Region (FIR) without submitting a flight plan and flying over three islets of the eastern Aegean, according to the Hellenic National Defence General Staff (GEETHA).

The two jets entered Athens’ FIR shortly after 10 a.m. on May 15 and flew at 29,000 feet over Farmakonisi, Lipsi and Arki said Kathimerini, and seven minutes later they flew over Ro and then over Farmokonisi 30 minutes later.

The Turkish jets were intercepted by Greek fighters as they are each time and with frequent mock dogfights, raising the chances of an accidental conflict that could bring the countries to the brink of battle or war.

Both Greece and Turkey belong to NATO but the defense alliance’s chief, Jens Stoltenberg, has made it clear he won’t intervene over repeated violations by Turkey, further emboldening Turkish President Recep Tayyip Erdogan to keep up the incursions.
