Turkish aeroplanes and helicopters illegally entered Greece’s airspace 141 times yesterday (15 May), the Hellenic National Defence General Staff reported.

According to Greek press reports, 20 Turkish F-16, 5 CN-235 maritime surveillance aircraft and 19 helicopters entered the Athens flight information region (FIR) without submitting a flight plan.

In all cases, Turkish aircraft were identified and intercepted by Greek fighters, while in nine cases the interception process resulted in near combat situations.

In addition, two Turkish missile boats entered Greek territorial waters off the southeast Aegean island of Agathonisi.

The vessels, which were taking part in a maritime exercise code-named Denizkurdu (Seawolf), stayed in Greek territorial waters for about 20 minutes. As Kathimerini journal reported, last month Agathonisi was described as a “Turkish island” by Turkey’s Minister of European Union Affairs Omer Celik.

Commission: Turkey must respect EU member states’ sovereignty Ankara must respect the sovereignty of EU member states over their territorial sea and airspace, European Commission spokesperson Maja Kocijancic told EURACTIV.com.

While the EU and the international community recognise the sovereignty of Greece over the Greek Aegean islands, Turkey has a list of issues regarding the delimitation of territorial waters, national airspace, exclusive zones, etc. Ankara also claims “grey zones” of undetermined sovereignty over a number of small islets, most notably the islets of Imia/Kardak.

The serious incidents occurred just a few hours after the meeting of Greek premier Alexis Tsipras with Turkish President Tayyip Erdoğan in Beijing.

The Greek Ministry of Foreign Affairs issued a strong communique saying that the incident “constitutes a flagrant violation of international law”.

“It is clear that there are forces in Turkey that do not want understanding and good neighbourly relations between the two countries,” the Greek ministry added.

In the meantime, tensions between Ankara and Berlin also escalated.

The German government is exploring the possibility of moving its troops out of Turkey’s Incirlik air base, which is crucial for the fight against ISIS, after a second German parliamentary delegation was prevented from visiting the Incirlik facility.

German news agency dpa quoted Wolfgang Hellmich, the chairman of the Bundestag Defense Committee, as saying “we’re not going to be blackmailed” by the Ankara government.

Berlin defies Ankara and grants Turkish soldiers asylum More than 400 Turkish state officials are seeking asylum in Germany. Despite Ankara insisting these applications be denied, Berlin has granted protection to military personnel in a number of cases. EURACTIV’s partner Der Tagesspiegel reports.

Commission warns Ankara

Contacted by EURACTIV.com, an EU spokesperson sent a strict message to Turkey, urging that it respect the sovereignty of the EU’s member states.

“The EU underlines that Turkey needs to commit itself unequivocally to good neighbourly relations and urges Turkey to avoid any kind of source of friction, threat or action directed against a member state, which damages good neighbourly relations and the peaceful settlement of disputes,” the spokesperson said.

The same official added that negative statements that damage good neighbourly relations should also be avoided.

“Moreover, the EU also stresses the need to respect the sovereignty of member states over their territorial sea and airspace,” the spokesperson told EURACTIV.

“At the Informal Meeting of Foreign Ministers (Gymnich) of last 28 April, the EU High-Representative and Vice-President Federica Mogherini recalled that good neighbourly relations are one of the core principles which Turkey is called upon to respect as a candidate country,” the EU official concluded.
