A Turkish unmanned aerial vehicle entered the Athens Flight Information Region and violated Greek national airspace on Friday morning in the area between Samothrace and Lemnos, prompting an immediate response from the Hellenic Air Force. A pair of Greek F-16 fighter jets scrambled to identify and intercept the drone, according to Protothema.gr.
The incursion came just hours after Turkey's Defence Ministry warned that a potential UAV base on Rhodes would "harm peace and stability in the Aegean," while referring to the possible adoption of "necessary measures," Protothema reported.
Athens reads intentions
Greek officials are trying to determine whether the recent series of moves from Ankara amounts to political and military signalling, or marks a return to a period of sustained field-level tension, according to the report. Messages from Ankara have multiplied in recent months, while efforts by Foreign Ministers Giorgos Gerapetritis and Hakan Fidan to find common ground toward a compromise agreement referring the delimitation of maritime zones to the International Court of Justice in The Hague have stalled.
There is currently no meeting planned between Prime Minister Kyriakos Mitsotakis and President Recep Tayyip Erdogan on the margins of the UN General Assembly, where, according to Protothema's analysis, any new understanding would be difficult to reach given the Turkish president's efforts in New York to capitalise politically on Turkey's growing regional role, including his positioning against Israel and initiatives such as the Mecca Alliance.
Maritime parks and the 'grey zones' theory
The drone incident follows Turkey's recent move to establish, via presidential decrees, two large marine parks in the northern Aegean and eastern Mediterranean, alongside a return to national airspace violations, this time carried out with armed Turkish F-16s rather than drones, developments Protothema describes as pushing Greek-Turkish relations into a difficult period.
According to the analysis, Turkey's maritime park plans encode its maximalist legal position: that islands are not entitled to maritime zones beyond their current six-nautical-mile territorial waters, and that islands should not factor into the median line delimiting the Aegean, a position that would effectively trap Greek islands within a Turkish continental shelf and areas of Turkish jurisdiction. The park in the northern Aegean is positioned between Lemnos and Samothrace, an area covering international waters and undelimited Greek continental shelf near the strait's exit, through which subsea interconnections between Lemnos and Thrace pass, meaning under Turkey's claims such projects would require Turkish approval.
Turkey has raised similar objections, including invoking its "grey zones" theory, in response to a string of earlier Greek initiatives: the April 2025 publication of Greece's Maritime Spatial Plan, based on the UN Convention on the Law of the Sea and EU acquis; Greece's subsequent moves on tourism spatial planning and renewable energy zoning; and attempts in July 2024 to survey for the GSI subsea power cable linking Cyprus and Crete, which were halted by the Turkish navy. The report notes Turkish objections were also raised over the median-line demarcation of two offshore blocks south of Crete, awarded to Chevron.
In recent weeks, majority ownership of the GSI cable project has passed to French company Meridiam, which will also take responsibility for delivering the project, while Cyprus has announced plans to begin developing the "Kronos" gas discovery in Block 6 of its exclusive economic zone.
Protothema's analysis frames the drone incursion and the new maritime parks as part of a deliberate signal from Ankara that it will not tolerate Greece exercising sovereign rights it regards as threatening Turkish interests, as articulated through Turkey's "Blue Homeland" doctrine, while also demonstrating that Turkey's focus on regional crises in the Black Sea, Middle East and Iran does not mean it is leaving the Aegean and eastern Mediterranean uncontested. The report also points to a domestic political dimension, with Ankara said to view Greece as acting with the backing of a new regional competitor, Israel, adding a further layer to the traditional Greek-Turkish dispute over the Aegean.
The analysis notes that Fidan referenced the Greece-Cyprus-Israel trilateral format last week while addressing Egypt in the context of the Mecca Alliance, characterising the trilateral as bisecting the eastern Mediterranean in a way that disregards Turkey and Egypt's own opposite coastlines.
