Eastern Mediterranean tensions rise over military drills and regional maritime pacts

Regional tensions in the Eastern Mediterranean intensified during the week of October 19, 2026, following the commencement of the multinational 'Eunomia 2026' military exercise. Involving Greece, Cyprus, France, and Italy, the drills took place in areas south of Kastellorizo and between Crete and Kastellorizo—waters where a French research vessel is expected to conduct seabed surveys for the Great Sea Interconnector project. Turkish media outlets labeled these initiatives as provocations, framing the exercises as an attempt to establish new facts in contested maritime zones.

Simultaneously, the political landscape shifted as the House of Representatives of eastern Libya voted on October 20 to ratify the controversial 2019 memorandum on maritime jurisdiction with Turkey. This decision marks a significant reversal from the Libyan parliament's previous 2020 rejection of the deal. In response, Israel and Egypt issued sharp condemnations. Israel's Ministry of Foreign Affairs explicitly accused Ankara of undermining regional stability, while Cairo declared the ratification legally invalid. These developments have deepened the divide between the regional powers, with Turkish commentators claiming the Libyan move weakens Greek diplomatic leverage, despite ongoing legal disputes regarding maritime borders.
