Greece has raised the eastern Libyan parliament's ratification of a contested maritime deal with Turkey at the U.N. Security Council, warning that it threatens security and stability in the eastern Mediterranean.
Greece's U.N. ambassador, Aglaia Balta, briefed the council during closed consultations on the instructions of Foreign Minister Giorgos Gerapetritis, diplomatic sources said. Greece holds a nonpermanent seat on the council through the end of 2026.
Mrs. Balta outlined the risks the agreement poses to the region, the sources said.
The 2019 memorandum, signed by Turkey and Libya's internationally recognized government in Tripoli, draws a maritime boundary between the two countries that ignores the Greek island of Crete.
Libya's House of Representatives, based in the east and aligned with military commander Khalifa Haftar, ratified it on Tuesday after years of opposition.
The European Union, Egypt and Israel have rejected the deal.
On Wednesday, EU foreign policy chief Kaja Kallas told Turkish Foreign Minister Hakan Fidan during talks that the agreement "infringes upon the sovereign rights of third states."
Mrs. Kallas' comments echoed a joint statement by top EU officials a day earlier calling the pact "null and void."
Athens says the ratification has no legal effect, and has vowed to protect its sovereign rights.
The dispute comes as Greece prepares to resume seabed surveys next month for an undersea power cable linking it to Cyprus. Turkey has cited the Libya deal to contest the cable's route.
Libya has been split between rival governments in the east and west since 2014.
