The upper air space over Kosovo - skies above 10,000 feet - will remain under the control of a Hungarian state company for "an indefinite period" after the current five-year agreement signed in 2014 "for the provision of air navigation services and other relevant activities in the designated airspace over Kosovo" expires on April 3.
Following his resignation from the post of foreign minister, Nikos Kotzias said that Greece was ready to extend its territorial waters in the Ionian Sea to 12 nautical miles. This came as surprise to Greece's political parties and drew a strong reaction from Turkey, which claimed that any extension of Greece's territorial waters in the Aegean would be considered a casus belli.
Turkish aircraft violated Greek airspace seven times at the northeastern, central and southeastern Aegean on Tuesday, in incidents that resulted in one dogfight between Greek and Turkish fighter jets.
The six Turkish F-16 jets which flew in three formations and the two CN-235 also infringed air traffic regulations five times.
The prime minister's office reacted to Monday's incident near Ro saying that the Turkish helicopter was flying near the eastern Aegean islet with its navigation lights out, but did not violate Greece's airspace.
The lights-out flight ostensibly occurred in the context of "safe provocativeness," it said, adding that such tactics carry the risk of potential accidents.
