UN Mission in Western Sahara Ends Operations
The Security Council failed to renew the MINURSO mandate, closing a 35-year peacekeeping mission.
Updated on Nov. 5, 2026 in Military
The UN Security Council did not agree on an extension of the MINURSO mandate, which expired on October 31, and the mission ceased operations after 35 years. Its only remaining task is to carry out its withdrawal.
Why it matters
The lapse ends a long-running UN presence in Western Sahara and leaves the withdrawal process dependent on cooperation from the parties involved. Movement at the Security Council is hoped for as the process moves forward.
MINURSO's operation of 35 years has ended, with 22 personnel having lost their lives in service. The withdrawal timeline and the parties' cooperation remain unresolved in the available record.
The players
MINURSO
The United Nations Mission for the Referendum in Western Sahara, a peacekeeping mission that operated for 35 years before its mandate lapsed.
UNIFIL
The United Nations Interim Force in Lebanon, a peacekeeping force that continues to operate in southern Lebanon and facilitate humanitarian access.
Israel Defence Forces
The military of Israel, which civilians in southern Lebanon have accused of detentions, access restrictions, and property confiscations.
The details
MINURSO's mandate expired on October 31 without renewal, and the mission has ceased operations apart from its withdrawal. Separately, UNIFIL peacekeepers in southern Lebanon continue implementing their mandate, facilitating humanitarian access and maintaining liaison with the parties. UN colleagues have conveyed civilian complaints about detentions, access restrictions, and property confiscations by the Israel Defence Forces, with some detainees released and properties returned.
Timeline
October 31, 2026: MINURSO mandate expired and the mission ceased operations.

Roadmap
The end of MINURSO closes a mission created under the 1991 Morocco–Polisario ceasefire, which was meant to organize a referendum that never took place. The lapse marks a clear departure from the UN's long-running role in the territory.
The end of MINURSO removes a UN-led presence from Western Sahara, and the remaining withdrawal depends on the parties' cooperation. Readers following UN peacekeeping should watch for Security Council movement on the process.
The takeaway
Peacekeeping missions depend on continued consent from the parties involved, and a failed Security Council renewal can end a 35-year presence with little notice. Watching Security Council votes offers an early signal of how such missions will be resolved.
