Europe’s two-track security strategy for Lebanon

As the mandate of the United Nations Interim Force in Lebanon (UNIFIL) approaches its scheduled expiry at the end of 2026, the European Union (EU) has reaffirmed its support for extending the peacekeeping mission while simultaneously expanding its own security assistance to Lebanon.

The parallel announcements underscore growing international concern over stability in southern Lebanon, where security remains fragile following months of conflict and continued tensions along the Lebanese-Israeli border.

European support for extending UNIFIL’s mandate

During a visit to Beirut, the EU’s High Representative for Foreign Affairs and Security Policy, Kaja Kallas, stressed that EU member states remain united in supporting the renewal of UNIFIL's mandate, considering its continued presence essential to preventing a security vacuum in southern Lebanon.

She noted that European countries have consistently maintained that a security vacuum in southern Lebanon must be avoided, adding that there is broad concern within the bloc about the prospect of the mission ending without an extension. According to Kallas, renewing the mandate would be “highly welcomed” and reflects the common position of EU member states.

During a joint press conference, Lebanese Minister of Foreign Affairs and Emigrants Youssef Raggi thanked the EU for its continued support for Lebanon and welcomed the decision to establish a mission under the Common Security and Defense Policy (CSDP). He also stressed the importance of EU support for Lebanon’s sovereign decision to place all weapons under the exclusive authority of the State, and to end the Israeli occupation of Lebanese territory.

UNIFIL, established in 1978 and significantly expanded following the adoption of United Nations Security Council (UNSC) Resolution 1701 after the 2006 Lebanon-Israel war, operates across southern Lebanon between the Litani River and the Blue Line separating Lebanon and Israel. The mission monitors the cessation of hostilities, supports the deployment of the Lebanese Armed Forces (LAF) in the south, facilitates humanitarian access, and assists in maintaining stability along one of the region’s most sensitive frontiers.

The issue has become increasingly urgent as diplomatic discussions continue over the mission’s future, with its current mandate due to expire at the end of the year.

New European Union Support Mission for Lebanon

While advocating for UNIFIL’s renewal, the European Union has also expanded its direct support for Lebanese security institutions.

On 12 October 2026, the Council of the European Union established the European Union Support Mission in Lebanon (EUSM Lebanon) under the bloc’s Common Security and Defense Policy (CSDP). The mission has been given an initial three-year mandate.

According to the Council, the mission aims to contribute to peace and security in Lebanon by strengthening state institutions and supporting the implementation of UNSC Resolution 1701. It will provide strategic advice and assistance to the LAF and the Internal Security Forces (ISF) in several priority areas, including territorial control, border security, internal security, and maritime security governance.

Kallas described the mission as an important evolution in EU-Lebanon security cooperation, reaffirming Europe’s commitment to Lebanon’s sovereignty, state institutions, and long-term stability.

European officials have indicated that the mission is expected to deploy approximately 150 civilian and military personnel, while emphasizing that the initiative is intended to complement, not replace, UNIFIL.

Strengthening the Lebanese Armed Forces

The newly established mission builds on several years of increasing European assistance to the Lebanese military.

Since 2022, the EU has provided €182 million in support to the LAF through the European Peace Facility (EPF). The latest assistance package, worth €100 million and approved in June 2026, focuses on enhancing the army’s operational capabilities in five principal areas: territorial control, multi-domain situational awareness, maritime security, protection of critical military infrastructure, and military healthcare.

The broader objective of the European Peace Facility is to improve the LAF’s capacity to monitor and secure Lebanon’s territory, reinforce state authority, uphold the state’s monopoly over arms, and strengthen the protection of civilians.

These initiatives form part of the EU’s wider strategy of reinforcing Lebanon’s national institutions amid ongoing political, economic, and security challenges.

UNIFIL reaffirms commitment until the end of its mandate

Amid growing speculation regarding the mission’s future, UNIFIL has stressed that its peacekeepers remain fully committed to carrying out their mandate until its final day.

In a recent statement, the mission said its personnel continue to conduct hundreds of operational activities every day on land and at sea, including joint operations with the LAF. Despite the operational challenges created by recent hostilities, peacekeepers continue to perform regular patrols, clear obstacles from roads, facilitate humanitarian missions, and provide essential assistance to displaced persons and vulnerable local communities.

UNIFIL added that since violence subsided toward the end of June, it has gradually increased the pace of its operational activities and intends to maintain that level through the remainder of its mandate.

The statement sought to reassure both local communities and international partners that the mission remains operational despite the uncertainty surrounding its future.

Concerns over a potential security vacuum

The debate over UNIFIL’s future has intensified because of concerns that its departure could leave southern Lebanon without an effective international monitoring mechanism.

The mission’s area of operations covers approximately 1,060 square kilometers between the Litani River and the Blue Line, including areas where security conditions remain particularly sensitive following the recent conflict with Israel.

Should UNIFIL’s mandate not be renewed, questions remain over which institution would assume responsibility for monitoring the Blue Line, documenting violations, facilitating coordination between the parties, and supporting stability in areas that remain difficult to access or are affected by Israeli military restrictions.

Although the LAF continue to expand their deployment in southern Lebanon, assuming all of UNIFIL’s current operational responsibilities would require additional personnel, equipment, logistical support, and sustained international assistance. In this sense, the EU’s simultaneous endorsement of a UNIFIL mandate extension and establishment of a new security support mission reflects a dual-track approach to Lebanon’s security challenges.
