Cyprus files UN complaint against Turkish maritime activities

Cyprus has submitted a formal letter to UN Secretary-General Antonio Guterres, protesting Turkish maritime activities in the Republic of Cyprus's continental shelf, exclusive economic zone, and seabed. The complaint, sent by Permanent Representative Maria Michail, concerns unauthorized underwater research and operations conducted by Turkish-flagged vessels, including the Oruç Reis, Denar Pathfinder, Denar Echo, and Kirici.

These activities, which took place between October 1 and October 25, 2026, are reportedly linked to a planned natural gas pipeline between Turkey and the occupied areas of Cyprus. The Cypriot government asserts that these actions violate its sovereignty and jurisdiction under international law, specifically citing the United Nations Convention on the Law of the Sea. The letter follows a previous complaint in August regarding an illegal memorandum of understanding signed between Turkey and secessionist entities in July 2026.
