UN Peacekeeping Mission in Western Sahara Ends After 35 Years

The Vote and Immediate Consequences

The United Nations peacekeeping mission in Western Sahara, known as MINURSO, ended operations on 1 November after 35 years. The Security Council failed to renew its mandate. Russia vetoed a U.S.-drafted resolution that supported Morocco's autonomy plan under Moroccan sovereignty. A competing Russian resolution to extend the mission received only three votes and failed. November 1 marked the start of the liquidation phase, with a smaller team overseeing the return of troop-contributing countries' assets and disposal of U.N. equipment.

Secretary-General António Guterres warned of the risk of escalation and called on all parties to exercise maximum restraint. Morocco welcomed the end of the mission, describing it as an instrument that internationalized the dispute. The Polisario Front, backed by Algeria, called the outcome unacceptable. The mission was established in 1991 after a U.N.-brokered ceasefire. It was tasked with monitoring the ceasefire and organizing a referendum on self-determination that never took place because of disagreements over voter eligibility.

Historical Mandate and Scale

MINURSO was authorized for 534 personnel. Its 2026-2027 budget exceeded $62 million. Top military contributors included Egypt, Ghana and Pakistan. Twenty mission personnel lost their lives during the deployment. The force maintained a presence of military observers, civilian staff and mine-action teams across the territory. About 200 civilian and military personnel from more than 35 countries served at the time of closure.

The territory, roughly the size of Colorado, is claimed by Morocco and by the Polisario Front, which seeks independence. Spain withdrew in 1976. Hostilities have continued at a low level despite the ceasefire. Last year the Security Council adopted a U.S.-backed resolution that described Morocco's autonomy plan as the most feasible solution. Russia abstained then but vetoed this year's text that would have further advanced the Moroccan position.

Reactions and Next Steps

Guterres stated that the United Nations remains ready to support dialogue through his Personal Envoy, Staffan de Mistura. He urged respect for the rights of the people of Western Sahara. Moroccan officials said the non-renewal closes the file at the U.N. Polisario representatives expressed concern that the absence of monitors increases risks for civilians. The U.S. and Russia each accused the other of blocking progress toward a political settlement.

The liquidation process will take weeks as equipment is repatriated. No new mandate was adopted, so the mission has no legal basis to remain. Regional stability depends on whether the parties maintain restraint without the presence of U.N. observers. The dispute has lasted half a century and involves mineral resources, fisheries and access to the Atlantic coast.

Longer-Term Outlook

Previous extensions of MINURSO occurred regularly since 1991. The abrupt end reflects deepening divisions between permanent members of the Security Council. Morocco has increased its control over the territory in recent years and received growing international recognition of its claims. The Polisario continues to operate from refugee camps in Algeria and maintains a military presence along the berm. Without a monitoring mission, verification of any future ceasefire violations becomes more difficult.

The Secretary-General's office will continue diplomatic efforts. The outcome leaves the political process without the institutional framework that has existed for three and a half decades. Both sides have indicated they will not accept unilateral changes to the status quo by force.
