The United Nations has begun winding down its peacekeeping mission in Western Sahara after 35 years, following a diplomatic confrontation between the United States and Russia that prevented the Security Council from extending the operation's mandate.
The United Nations Mission for the Referendum in Western Sahara, known as MINURSO, formally ceased its peacekeeping operations on Sunday, November 1, after its mandate expired at the end of October.
The mission had operated in the disputed North African territory since 1991, monitoring a ceasefire between Morocco and the pro-independence Polisario Front while supporting efforts to organise a referendum on the territory's political future.
Its closure marks a significant turning point in one of Africa's longest-running territorial disputes and raises questions about security, diplomatic negotiations and the future of the Sahrawi people's right to self-determination.
United Nations confirms mission closure
In a statement issued on Sunday, UN Secretary-General António Guterres confirmed that MINURSO had entered a formal liquidation period following the Security Council's failure to renew its mandate.
A reduced United Nations team will remain temporarily to supervise the orderly withdrawal of personnel and equipment.
The team, reporting to the UN Department of Operational Support, will coordinate the return of equipment belonging to countries that contributed personnel to the mission and oversee the disposal or reassignment of UN-owned assets.
The organisation has not announced a precise date for completing the withdrawal.
Guterres thanked the mission's personnel for their service and acknowledged their contribution to efforts to maintain stability in the territory.
Twenty MINURSO personnel died during the mission's 35 years of operation, according to the United Nations.
The secretary-general also warned that the withdrawal could create additional security risks.
He called on the parties to exercise restraint and avoid actions that could intensify hostilities.
US and Russia fail to agree on the mission's future
The closure follows an unsuccessful Security Council meeting on Friday, October 30.
The United States introduced a draft resolution that would have extended the UN operation for another year while substantially changing its mandate.
The proposal supported Morocco's autonomy plan as the basis for resolving the territorial dispute and would have reduced the mission's military component.
It also proposed removing the reference to a referendum from the mission's name.
Russia vetoed the American proposal, arguing that the Security Council should not determine the territory's sovereignty in advance of negotiations.
A competing Russian resolution, which sought to preserve the existing peacekeeping arrangement for another year, also failed to secure approval.
Neither proposal was adopted.
As a result, the mission's existing mandate expired on October 31 without a replacement agreement.
The diplomatic disagreement reflects competing international positions over whether Western Sahara should become independent or remain under Moroccan sovereignty with a degree of autonomy.
A territorial dispute dating back to 1975
Western Sahara is a sparsely populated territory along Africa's Atlantic coast, rich in fisheries and mineral resources.
It was administered by Spain until 1975, when Spanish colonial rule ended.
Morocco subsequently established control over most of the territory, while the Polisario Front pursued independence for the Sahrawi people.
The dispute developed into an armed conflict that continued for more than a decade.
In 1991, a United Nations-brokered ceasefire created the conditions for MINURSO's deployment.
The mission was tasked with monitoring the ceasefire and helping prepare a referendum through which the people of Western Sahara could determine their political future.
However, the referendum was never held.
Disagreements over voter eligibility, political status and the terms of self-determination prevented the process from advancing.
MINURSO remained in the territory as the international community attempted to negotiate a settlement.
Morocco welcomes the development
Morocco's government welcomed the Security Council's failure to renew the mission.
The Moroccan royal palace said the decision should lead to the departure of MINURSO personnel and equipment from the territory.
Rabat considers Western Sahara part of its national territory and has proposed an autonomy arrangement under Moroccan sovereignty.
The proposal has gained support from several Western governments, including the United States, France and the United Kingdom.
Morocco argues that autonomy offers a practical basis for resolving the dispute while maintaining territorial integrity.
Its foreign minister, Nasser Bourita, said the country would continue respecting its ceasefire commitments despite the departure of the UN peacekeeping operation.
The end of MINURSO's mandate does not itself constitute a new international legal determination of sovereignty over Western Sahara.
Polisario Front and Algeria oppose the outcome
The Polisario Front condemned the mission's non-renewal, describing it as a setback for the peace process and the Sahrawi people's right to self-determination.
The movement continues to advocate independence and maintains that the people of Western Sahara should be allowed to determine their future through a legitimate political process.
Algeria, which supports the Polisario Front and hosts Sahrawi refugee camps, also criticised the Security Council outcome.
Its Foreign Ministry expressed regret over the failure to extend the mission and accused the American proposal of favouring Morocco's position.
The dispute remains a major source of tension between Morocco and Algeria.
The two countries severed diplomatic relations in 2021 and have maintained sharply different positions on Western Sahara.
The closure of the UN operation could deepen mistrust between the neighbouring countries, although no new military confrontation was confirmed as a consequence of Sunday's announcement.
Concerns over renewed hostilities
The original ceasefire between Morocco and the Polisario Front broke down in 2020.
Since then, the territory has experienced intermittent hostilities and continuing military tension.
MINURSO's presence provided an international mechanism for observing developments and supporting efforts to prevent escalation.
The withdrawal removes that peacekeeping arrangement without an announced replacement.
Humanitarian organisations have warned that the loss of international monitoring could increase risks for civilians and complicate efforts to prevent further violence.
Oxfam said the removal of MINURSO's monitoring and de-escalation functions could undermine regional stability.
The United Nations has similarly expressed concern about the security situation.
However, the end of the mission does not mean that a new war has begun or that large-scale fighting has been confirmed.
The immediate development is the termination of the UN peacekeeping mandate and the beginning of its withdrawal.
What happens to the Sahrawi people?
The political future of Western Sahara remains unresolved.
The United Nations continues to classify the territory as non-self-governing, and Guterres has reaffirmed the importance of a political solution that provides for self-determination.
Large numbers of Sahrawi refugees continue to live in camps near Tindouf, Algeria, where humanitarian assistance remains essential.
The loss of the peacekeeping mission has raised concerns about the international mechanisms available to support a settlement.
However, the United Nations has not abandoned its diplomatic involvement.
Guterres said the organisation remains prepared to support dialogue through his personal envoy for Western Sahara, Staffan de Mistura.
That process will continue separately from the discontinued peacekeeping operation.
The distinction is significant: the UN's military and monitoring mission has ended, but its diplomatic efforts have not been formally terminated.
Wider implications for Africa
Western Sahara remains one of the most sensitive political disputes in North Africa.
Its unresolved status has influenced relations between Morocco and Algeria, shaped regional diplomacy and complicated efforts to strengthen cooperation across the Maghreb.
The African Union has historically supported the principle of self-determination, while member states have maintained differing positions on the territory's final political status.
The departure of MINURSO also raises wider questions about the ability of the United Nations Security Council to maintain peacekeeping operations when its permanent members disagree.
The Security Council's inability to renew a mission that operated for 35 years demonstrates how disagreements among major powers can directly affect regional security arrangements.
For African governments, the development is relevant to debates about sovereignty, decolonisation, conflict prevention and the role of international peacekeeping.
What happens next
The United Nations will now concentrate on withdrawing MINURSO's personnel and equipment while continuing diplomatic efforts through Staffan de Mistura.
Morocco and the Polisario Front remain divided over the territory's political future.
Algeria continues to support Sahrawi self-determination, while Morocco maintains that autonomy under its sovereignty offers the most realistic settlement.
No new agreement replacing the peacekeeping mission has been announced.
The immediate priority for the United Nations is to complete the withdrawal without creating additional security risks.
The longer-term challenge is finding a political solution acceptable to the parties while protecting the rights and security of the people of Western Sahara.
After 35 years, MINURSO's peacekeeping operations have ended.
The territorial dispute it was established to help resolve remains unsettled.
