Israeli Foreign Minister Eli Cohen addressed the United Nations Security Council with a "blunt warning" about the possibility of an "regional war" due to the situation in South Lebanon, according to Israel's Channel 12 on Tuesday.

Cohen warned in an "unusual" letter that if Security Council Resolution 1701 is not fully implemented and the presence of Hezbollah’s "Radwan Force" continues on the border, and if the United Nations Interim Force in Lebanon (UNIFIL) does not use all its capabilities to prevent any illegal military presence south of the Litani River, a "regional war" could break out.

Cohen wrote: "For the sake of regional stability and to prevent further escalation – the upcoming discussion of the United Nations Security Council must adopt a completely different approach to end the serious violations committed by Hezbollah and other terrorist organizations on the border."

Security Council Resolution 1701, which ended the Second Lebanon War in 2006, stipulates that Hezbollah is not allowed to operate in South Lebanon and that the entire South Lebanon area must be free of any armed presence and weapons other than those belonging to the Lebanese government.

The mission of UNIFIL, which operates as a buffer zone between Lebanon and Israel in the border area, is to implement Resolution 1701.

Earlier this month, the U.S. envoy, Amos Hochstein, issued a veiled warning to Lebanon about a fate similar to what is happening in the Gaza war if the escalation continues in the border area with Israel, emphasizing the necessity of implementing United Nations Security Council Resolution 1701.
