The European Union threatened to cancel a summit with Turkey next month because of Turkish tensions with Cyprus over energy exploration, the latest sign of deteriorating relations between Ankara and EU capitals.
EU President Donald Tusk lashed out at Turkey after its navy prevented drilling by Italy-based Eni SpA in waters that are part of Cyprus’s exclusive economic zone, forcing the company to relocate its vessel. Earlier this month, a Turkish navy ship rammed a Greek coast-guard vessel off Aegean islets over which Ankara claims sovereignty.
