Greece expelled the Libyan ambassador, angered by an accord between Libya and Turkey mapping out a sea boundary between the two countries close to the Greek island Crete.
Libya called the move unacceptable. Turkey dismissed it as outrageous.
Greek Foreign Minister Nikos Dendias said the Turkey-Libyan accord was a “blatant violation of international law”, telling a news briefing ambassador, Mohamed Younis AB Menfi, had 72 hours to leave the country.
The move did not mean Greece was severing diplomatic relations with Libya, Dendias said. Another foreign ministry official said Libya “deceived” Greece.
“This is a legally invalid document,” Greek Prime Minister Kyriakos Mitsotakis told parliament.
“Not only is it geographically and historically invalid — wiping Greek islands off the map — it led Turkey to an unprecedented diplomatic isolation,” he said.
“It’s a piece of paper nobody recognises.”
Libyan Foreign Minister Mohamed Siyala told Reuters Greece’s decision was not acceptable and Libya would reciprocate if Greece had diplomatic representation in the country.
“It is Greece’s right to go to the International Court of Justice and legal channels to remove confusion. But to take the stand of expelling the ambassador, summoning him and escalating the situation, is unacceptable to the Libyan government,” Siyala said.
OIL, GAS RESERVES
Turkish Foreign Minister Mevlut Cavusoglu condemned the move. “Expelling an ambassador because of the agreement signed is not mature behaviour in diplomacy. This is outrageous,” he told reporters in Rome.
The expulsion is the latest twist in a saga of Mediterranean states jostling to claim untapped oil and gas reserves in the region.
Turkey and the internationally recognised government of Libya signed the accord in November defining boundaries and a deal on expanded security and military co-operation, a step Turkey said was protecting its rights.
Greece called the accord absurd because it ignored Crete between Turkey and Libya.
“The text of this agreement carries the signature of the Libyan foreign minister. It is the same person who, in September, assured the Greek side otherwise,” Dendias said.
Mitsotakis said the speaker of Libya’s parliament would be in Athens for consultations.
Greece and Turkey are at odds over issues ranging from mineral rights in the Aegean Sea to ethnically-split Cyprus. Tensions also run high because of Turkish drilling off Cyprus and the European Union prepared sanctions against Turkey in response.
On Thursday, Cyprus said it had petitioned the International Court of Justice (ICJ) to safeguard its offshore rights. It said an attempt to deliver notice of its intentions to the Turkish embassy in Athens was not accepted.
Turkish Foreign Ministry spokesman Hami Aksoy told reporters in Ankara Turkey was not aware of any petition.
