A Turkish Navy aircraft in the middle of Aegean?

In the last weeks we have followed several flight of Turkish drones both off the coast of Cyprus and along the Greek-Turkish maritime border on the Aegean Sea.

Today, however, we followed a different flight than usual. An unidentified aircraft, with callsign TURNA65 flew over the southern Aegean southbound, circled the island of Rhodes before disappearing from the radar (Flightradar24).

After a quick search, via Twitter, we can suppose that it was an aircraft of the Turkish Navy (TURkish NAvy). Probably a MELTEM II CASA CN-235 Maritime Patrol aircraft.

We do not know if the aircraft was intercepted by the Hellenic Air Force or simply monitored, having entered Greek air space, presumably without authorization.
