Caretaker Prime Minister Najib Mikati said Wednesday that efforts should be exerted to prevent Lebanon from being turned into “an arena for armed conflicts starting from the south.”

“The relevant U.N. resolutions must be implemented in order to put an end to Israel’s expansionist ambitions, and accordingly not linking Lebanon’s stability and interests to extremely complicated conflicts and endless wars,” Mikati added, during a joint press conference in Beirut with the Vatican’s Secretary of State, Cardinal Pietro Parolin.

Bou Habib will then head to the United States for talks with U.S. officials in Washington and U.N. officials in New York. The minister will also visit Canada to meet with his Canadian counterpart.
