A pair of Turkish fighter jets conducted an unauthorized flight over the eastern Aegean island cluster of Oinousses on Tuesday morning.
The violation of Greece's airspace was recorded at 10.27 a.m. and comes on top of a recent spate of such breaches.
The two F-16 jets flew at an altitude of 24,000 feet above the Greek islands.
Turkey on May 4 denied allegations that Turkish forces had harassed a helicopter carrying Greek Defense Minister Nikolaos Panagiotopoulos over the Aegean Sea.
"Any harassment of the helicopter carrying Greece's national defense minister on board is out of the question," said Turkish Foreign Ministry spokesman Hami Aksoy in a statement.
