Greece's Coast Guard said it rescued 49 migrants from a dinghy sailing off the northern city of Alexandroupolis early Thursday morning.
The rescuees were transferred safely to the port of Alexandroupolis where the local port authority will investigate the incident.
The coast guard did not provide details on their nationalities.
In what is seen as a response to an ongoing annual exercise by the Hellenic Navy in the Aegean, Turkish jets violated Greek national airspace 99 times on Tuesday, according to the Hellenic National Defense General Staff (GEETHA).
Forty-six of those violations were conducted by fighter jets and the other 53 by CN-235 surveillance aircraft.
Greece's Coast Guard rescued early Thursday morning 19 migrants who were on board an inflatable dingy in the sea northeast of the islet of Farmakonisi in the eastern Aegean.
They were all transferred to the island's port, state-run news agency ANA-MPA reported.
No further details were available on the rescuees or their health.
An accident was narrowly averted on Friday after a Turkish F-16 fighter jet reportedly harassed a Greek Super Puma helicopter, according to reports that emerged on Saturday.
The incident occurred shortly before noon south of the eastern Aegean islet of Farmakonisi as the Super Puma conducted a search for a boat carrying illegal migrants.
A Hellenic Coast Guard vessel on Monday intercepted a smuggling boat carrying 22 undocumented migrants off the Aegean island of Farmakonisi.
The migrants, whose ethnic origin was unknown, were transferred to the nearby island of Leros where they were to be hosted at a reception center to undergo registration.
The migrants were said to be in good health.
