Lebanon warned Israel on Sunday against any “aggressive action” in disputed waters where both states hope to develop offshore energy, after a ship arrived off the coast to produce gas for Israel.

President Michel Aoun said any activity in the disputed area would amount to an act of aggression and a provocation, after the arrival of the natural gas storage and production ship operated by London-based Energean.

Israel says the field in question is within its exclusive economic zone, not in disputed waters.
