Lebanon’s army will use use every available means to confront any potential “Israeli aggression” no matter the cost, its commander said on Monday.

“I affirm again our categorical rejection of the Israeli enemy infringing on Lebanon’s sovereignty and its sacred right to exploit all its economic resources,” the Lebanese army quoted General Joseph Aoun as saying on Twitter. “The army will not spare any method available to confront anyIsraeli aggression, whatever that costs.”

US diplomats have mediated recently between the two countries after a surge in tensions over a border wall which Israel is building and over Lebanon’s decision to explore for offshore energy near disputed waters.
