On Sunday, Turkey extended a navigation advisory (NAVTEX) regarding seismic surveys for oil and natural gas in the eastern Mediterranean, south of the island of Kastellorizo, until Thursday.
The legality of the Turkish NAVTEX, which is being contested by Greece, was to expire Sunday at midnight.
On the same day, the Greek advisory reserved areas in the wider area of southeastern Crete, Karpathos, Rhodes and south of Kastellorizo from Tuesday through Thursday.

The two NATO countries have been engaged in a long dispute over the divided island of Cyprus as well as maritime zones and exclusive economic claims in the area, with dialogue prospects recently diminishing over renewed tensions in the region.

On Friday, Turkish President Recep Tayyip Erdogan announced that Turkey has carried out the largest natural gas reserve exploration in the Black Sea.
