Paris and Beirut are advocating for the extension of the United Nations Interim Force in Lebanon (Unifil) beyond its current mandate expiration at the end of this year, despite opposition from Israel. The Lebanese government described it as “premature” to end the mission on December 31 and called for the continuation of the existing arrangement for a limited period in a letter submitted to the UN Security Council earlier this month.

France and most other Security Council members have shown support for Lebanon’s position during recent discussions, according to sources familiar with the matter. However, Israel, which continues to control significant areas in southern Lebanon and has conducted recent military strikes following escalations with the militant group Hizbollah, strongly opposes extending the mission. Hizbollah, backed by Iran, has rejected international calls for its disarmament.

The United States has expressed support for concluding Unifil’s five-decade deployment, one of the UN’s longest-running peacekeeping missions established in 1978 after clashes between Israel and Palestinian militants in Lebanon. Yet, it remains uncertain whether Washington would veto efforts to prolong the mission. One source indicated that the U.S. has only recently acknowledged that certain aspects of Unifil’s responsibilities still need to be maintained, but the precise approach is unclear. Official statements from both the U.S. and French governments on the issue were not provided.

Unifil originally deployed troops from around 50 countries to monitor ceasefires between Israel and Hizbollah, and its mandate and troop numbers have expanded over time in response to ongoing regional instability. Israel’s ambassador to the United Nations, Danny Danon, criticized attempts to extend Unifil during a closed-door Security Council meeting, stating that the decision to end the mission had already been made and should not be reversed.

Lebanese officials and their international backers argue that ending the mission abruptly could create a security vacuum, potentially destabilizing the already volatile southern Lebanon region. In his letter, Lebanon’s ambassador to the UN, Ahmad Arafa, urged a thorough reassessment before terminating the mandate to prevent any security gaps.

As negotiations continue, the fate of Unifil’s deployment remains uncertain amid differing positions among key Security Council members and regional stakeholders.
