Greece has said it is expelling the Libyan ambassador to the country, angered at an accord signed on November 27 between Libya and Turkey mapping out a sea boundary between the two countries close to Crete.
Mohamed Younis AB Menfi had 72 hours to leave the country, Greek Foreign Minister Nikos Dendias told a news briefing on Friday.
Dendias called the Turkey-Libyan accord a "blatant violation of international law".
The Libyan-Turkish agreement could complicate Ankara's disputes over offshore energy exploration in the Mediterranean with nations including Greece, which sees the move as infringing its sovereign rights.
Efthymios Tsiliopoulos, an analyst at the Greek Defence News website, talks to Al Jazeera about the dispute.
