Turkey insists on right to drill for energy reserves off Cyprus

Dispute likely to escalate after Nicosia said it would seek to arrest anyone caught drilling

Tensions over energy resources in the eastern Mediterranean have risen sharply after Turkey said it would "exercise its sovereign rights" to drill off Cyprus in flagrant defiance of warnings from western allies.

As the dispute over potential gas reserves intensified, Ankara insisted its state-of-the-art drilling ship, the Fatih, and its support vessels would begin operations in waters viewed by the EU as being within the island's exclusive economic zone.
