Greece has confirmed its readiness to use all its diplomatic and military might to defend its sovereignty against what it calls hostile plans by Turkey, after signing a memorandum of understanding with Libya.

Greek Prime Minister Kyriakos Mitsotakis said in a speech to his country's parliament that Athens and its powerful diplomatic allies are ready to defend Greece's water borders, indicating that high-ranking Greek officials are preparing to visit the countries of the Middle East to discuss the signed agreement.

The Turkish Foreign Ministry said that statements made by Greece and the European Union (EU) on Turkey's new hydrocarbons agreement with Libya have "no importance or value."
