The United Nations Security Council has voted to extend the mandate of the United Nations Interim Force in Lebanon (UNIFIL) for a final time until December 31, 2026, according to official decisions. Operations will cease on that date, initiating an organized and safe withdrawal lasting up to a year, with the objective of making the Lebanese state the sole security authority in the south. However, the transition faces severe risks while parts of the southern region remain under Israeli control, the disarmament of Hezbollah stalls, and cross-border strikes continue.
Paris Summit and International Support for the Lebanese Army
To address looming security gaps, Paris hosted a meeting on September 17 bringing together Arab and European military leaders and officials. According to Reuters, participants discussed post-UNIFIL arrangements and the operational needs of the Lebanese army, amid widespread concerns that an international withdrawal could trigger a serious security vacuum without prior readiness. The core strategy agreed upon by Beirut, Paris, and international partners places the Lebanese military at the center of future security structures, gradually assuming full responsibility in the south.
Proposals evaluated during the Paris talks include supplying the military with training, equipment, intelligence information, and military guidance. Officials also examined establishing a non-UN international or European mission to support Lebanese forces once UNIFIL concludes its tenure. While no final formula has been locked in, France has proposed creating a special international coalition at the request of the Lebanese government. European nations have expressed readiness to help monitor security arrangements, accompany retreating Israeli forces, and support the disarmament of Hezbollah.
Three Major Risks Threatening the Southern Border Transition
The transition plan confronts three distinct operational hurdles before the December 31, 2026 deadline. The first major risk involves an immediate security vacuum. UNIFIL currently does much more than monitor border zones; the force coordinates between hostile parties, escorts humanitarian convoys, secures UN access to isolated areas, and provides direct international oversight. UNIFIL Commander General Diodato Abagnara warned that a smooth transition is essential, noting that handing over responsibilities presents acute difficulties in sectors currently occupied by Israeli forces.
Field friction highlights these ongoing dangers. On September 18, the Lebanese army reported that an Israeli force approached an observation point near Deir Mimas–Marjayoun and deployed sound grenades. The incident triggered a high-alert standoff before the Israeli unit withdrew following communications through the special Lebanese military coordination group. The Lebanese army had warned days earlier that continuous Israeli attacks and demolition operations in the south undermine stability and threaten existing arrangements.

The second primary risk centers on the enforcement and monitoring of agreements. The post-UNIFIL phase is tied directly to implementing the framework agreement reached by Lebanon and Israel in June under US mediation. The proposed arrangement requires the Lebanese army to advance and secure the south in tandem with an Israeli withdrawal and the dismantling of Hezbollah’s military wing. Because any setback in one track threatens to derail the entire process, establishing a credible verification mechanism remains a core discussion point for France and its allies.
The third risk affects civilian populations directly. Beyond military concerns, southern towns rely heavily on UNIFIL to facilitate daily movement and humanitarian access, particularly in zones under Israeli control. In the border town of Rmeish, residents fear that the departure of international peacekeepers will deepen their isolation and choke off deliveries of fuel, food, and aid. The recent conflict caused more than 4,300 deaths and displaced approximately 300,000 people, according to Reuters figures.
Expert Insight: Moving from a nearly fifty-year international military buffer to sovereign domestic control is not merely a force rotation; it is a complex political and operational restructuring that requires robust external backing to prevent local instability from spiraling.
Parallel Tracks Ahead of the December Deadline
With time running short, Beirut, Paris, and international partners are pressing forward on two parallel tracks: boosting the capabilities of the Lebanese army and agreeing on an international safety net. France is working to mobilize an international conference to support both the military and internal security forces. Consultations regarding a specialized coalition or a renewed European security footprint remain active as the clock ticks down toward the final withdrawal window.
During the phased withdrawal period itself, UNIFIL maintains a mandate to protect UN personnel, facilities, and supply convoys while keeping field awareness around its positions. However, these protective functions will wind down step-by-step as the international force completes its exit. Analysts expect intense diplomatic and logistical maneuvering throughout the coming months as regional and European stakeholders attempt to finalize a viable framework before the end of 2026.
