Athens has accused Ankara of trying to "fabricate history" after the Turkish Foreign Ministry issued a statement denouncing comments by the Greek political class on the anniversary of the Pontic Genocide, the massacre of ethnic Greeks by the Turks during World War I and the subsequent Greek-Turkish war.
Two Turkish F-16 fighter jets entered Athens' Flight Information Region (FIR) without submitting a flight plan at 2.19 p.m. Thursday and flew over Oinousses, in the eastern Aegean, at 26,000 feet.
Two minutes later, the two jets flew over Panagia islet at 21,000 feet.
The Turkish aircraft were intercepted by Greek jets in line with international rules of engagement.
There is evidence of a sharp increase in aggressive behavior by Turkish security forces in both the Aegean and at the Evros land border, Kathimerini has learned.
Late on Wednesday, officers of Turkey's special forces fired over a Greek military vehicle that had been stationed on the Greek side of the border, Kathimerini reports.
