Turkey and Libya have signed a pact dividing control of the waters of the Mediterranean between them, a grab that virtually blockades the offshore gas and oil fields of Israel, Egypt, Cyprus and Greece. It also overrides those countries’ economic zones. Israel, deeply deadlocked in its efforts to form a government, has not reacted. DEBKAfile: The Turkish-Libyan siege overrides the Mediterranean rights of the littoral nations and sets up a major barrier against plans for laying pipelines to carry their gas and oil to their primary export markets in Europe. This crude action may be likened to China’s unilateral declaration of sovereignty over South China Sea islands.
