A Turkish UAV incursion into the Athens FIR and Greek national airspace on Friday morning prompted an immediate response from the Greek Air Force, amid renewed tensions between Athens and Ankara.
The unmanned aerial vehicle was reportedly operating in the area between Samothrace and Lemnos when it entered the Athens Flight Information Region and violated Greek airspace.
Greek F-16 jets scrambled
The Greek Air Force activated the required procedures, with a pair of F-16 fighter jets taking off to identify and intercept the Turkish UAV.
The incident came just hours after Turkey’s Defence Ministry warned that any possible installation of a UAV base on Rhodes would “harm peace and stability in the Aegean” and referred to the possibility of taking “necessary measures”.
The Turkish UAV incursion has added to a series of recent developments that have raised concerns in Athens over Ankara’s intentions.
Greek authorities are assessing whether Turkey’s latest moves are intended primarily as a show of force and political messaging or signal a return to more frequent on-the-ground provocations and uncontrolled escalation.
Tensions over maritime issues
The latest incident follows months of difficulties in efforts by Greek Foreign Minister George Gerapetritis and his Turkish counterpart Hakan Fidan to find common ground for an agreement that could refer the delimitation of maritime zones to the International Court of Justice in The Hague.
There are currently no plans for a meeting between Greek Prime Minister Kyriakos Mitsotakis and Turkish President Recep Tayyip Erdogan on the sidelines of the UN General Assembly.
The Greek government is also expected to face increased pressure to respond to any attempt by Turkey to create new facts on the ground while avoiding an escalation that could draw the attention of US President Donald Trump.
Return of airspace violations
Greek officials are also monitoring Turkey’s recent moves over the establishment of two large marine parks in the North Aegean and eastern Mediterranean, as well as the reported return to violations of Greek national airspace by Turkish military aircraft.
The developments have raised concerns that Greek-Turkish relations could be entering another difficult period.
Athens is expected to continue defending its sovereign rights through infrastructure and other initiatives, while seeking to prevent Turkey from imposing de facto restrictions on activities such as fishing and scientific research in areas of international waters.
A further concern is Ankara’s repeated references to so-called “grey zones” in the Aegean, which Athens considers incompatible with efforts to begin substantive discussions on maritime delimitation.
Athens Declaration under pressure
The Athens Declaration, which helped establish a period of relative calm between the two countries, has also come under renewed scrutiny.
Although Greece and Turkey continue to refer to the declaration in the absence of another framework, differences over its interpretation have weakened its practical impact.
The declaration contributed to a prolonged period without the frequent airspace activity that had previously characterised Greek-Turkish relations, allowing Athens to focus on other priorities, including its defence programme.
However, recent developments suggest that the period of relative calm may be coming under increasing strain.
Disputes over maritime zones
Greece’s publication of its Maritime Spatial Planning in April 2025 signalled its intention to exercise its sovereign rights within its territorial waters and its jurisdiction in international waters in accordance with the UN Convention on the Law of the Sea and the EU acquis.
Turkey responded by publishing its own unofficial maritime planning map, which overlapped with areas claimed by Greece.
Since then, disputes have also emerged over marine parks, offshore renewable energy projects and the electricity interconnection between Cyprus and Crete.
The developments surrounding the Great Sea Interconnector and the planned exploitation of the Kronos gas field in Cyprus’ Exclusive Economic Zone have added further strategic significance to the wider dispute.
Wider regional rivalry
The Greek-Turkish dispute is increasingly unfolding against the backdrop of broader geopolitical competition in the eastern Mediterranean.
Turkey has stepped up its regional role while strengthening its ties with countries including Saudi Arabia and Pakistan. At the same time, Greece has deepened cooperation with Cyprus, Israel and other regional partners.
The latest Turkish UAV incursion therefore comes at a time when disagreements between Athens and Ankara extend beyond traditional disputes in the Aegean and increasingly intersect with wider energy, defence and geopolitical developments.
