UN Western Sahara Mission MINURSO Enters Liquidation as Mandate Expires After Security Council Deadlock

The United Nations mission in Western Sahara entered a new and uncertain phase on Sunday, November 1, 2026, as its mandate expired without a renewal from the Security Council. The mission, known as MINURSO, has operated in the disputed territory since 1991, monitoring a ceasefire and working toward a political settlement of a conflict that has lasted for half a century. Its mandate, last extended by Resolution 2797 in 2025, ran through October 31, 2026 — and when that date passed, no replacement resolution was in place.

According to the United Nations, November 1 marked the beginning of the mission’s liquidation phase. Secretary-General António Guterres expressed appreciation for the mission’s role since its establishment, particularly in monitoring the ceasefire and creating conditions conducive to a political settlement. The announcement does not by itself set out a day-by-day withdrawal timetable, and reports checked for this article did not publish a detailed schedule for the departure of personnel and equipment. What is confirmed is the legal change: the mandate that authorised the mission has expired, and the liquidation phase has begun.

How the Security Council Deadlock Happened

The deadlock came on Friday, October 30, when the Council considered two competing drafts and adopted neither. The United States draft, which would have extended the mission for another year, drew 11 votes in favour, one vote against and three abstentions. The single vote against came from Russia, a permanent member, so its veto blocked the resolution even though it had majority support. The United States text would also have renamed the mission by dropping the word “Referendum” from its title, making it the United Nations Mission in Western Sahara, and would have put Morocco’s autonomy plan forward as the sole basis for negotiations, with a reduced military component.

Russia then tabled a counter-draft for a technical extension of the mission on its existing terms. That draft failed as well, drawing only three votes in favour, one vote against and 11 abstentions — short of the nine affirmative votes required for adoption. The two failures left the Council without an agreed renewal, an unusual outcome for a mandate that had previously been extended routinely each year. The dispute at the heart of the votes was not only about the mission’s future, but about the direction of the peace process itself: whether talks should be anchored in Morocco’s autonomy plan, or whether the referendum idea that gave MINURSO its name should be preserved.

The mandate that authorised the mission has expired, and the liquidation phase has begun.

What the Parties Said

Morocco welcomed the failure to renew the mandate. Its Royal Cabinet called the outcome an important evolution and a significant step toward the definitive closure of the Western Sahara file at the United Nations, and said the mission’s presence — personnel, vehicles, equipment and symbols — should cease in the coming days, turning what it described as a page of 35 years. Morocco’s two legislative chambers were also scheduled to hold a special joint session on Monday, November 2, to review the latest developments in the dispute.

A Polisario representative criticised the United States proposal, according to contemporaneous reporting, reflecting the other side’s objection to a text that would have removed the referendum reference and anchored negotiations in autonomy under Moroccan sovereignty. The United States ambassador, Michael Waltz, said after the vote that a referendum had never taken place because of longstanding disagreements over voter eligibility, while Russia’s ambassador described the United States text as a unilateral approach that exceeded the Council’s authority on sovereignty. Those positions show why the vote was about more than procedure: the two drafts represented different answers to a conflict that has remained frozen for decades.

• MINURSO was established in 1991 to oversee a settlement plan and a ceasefire between Morocco and the pro-independence Polisario Front.
• Its mandate was last extended by Resolution 2797 (2025), running through October 31, 2026.
• The United States draft won 11 votes but was vetoed by Russia; the Russian draft won only 3 votes and failed.
• The United Nations said November 1 marked the beginning of the mission’s liquidation phase.
• The referendum at the centre of the mission’s name has never taken place.

Why This Mission Mattered

Western Sahara is a disputed territory on Africa’s Atlantic coast, claimed by Morocco and by the Polisario Front, which seeks independence. MINURSO was created to oversee a settlement plan and a ceasefire, and its teams have monitored the territory’s ceasefire lines for decades. Even though the promised referendum never happened, the mission’s presence has been part of the architecture that kept the dispute managed rather than fought over at full scale. The work of United Nations missions in other conflicts shows how much weight such monitoring can carry, and how difficult it can be to replace once it is gone.

The expiry also comes at a moment when the United Nations itself is under strain in several theatres at once. The organisation has in recent days been dealing with the death of a Yemeni staff member in Houthi custody, a reminder of the risks faced by United Nations personnel in the field. For Morocco itself, the diplomatic shift arrives alongside a wider story of change in the country, including large solar power projects in its desert regions. The Western Sahara decision, however, stands apart: it is a Security Council outcome with direct consequences for a territory whose status remains unresolved.

What to Watch Next

What to watch next is what the article has already set out: whether the United Nations publishes a detailed withdrawal schedule for MINURSO personnel and equipment, whether Morocco’s parliament session on November 2 signals a new diplomatic push, whether the Polisario Front responds with its own proposals, and whether the Security Council returns to the file with a new text. Until those questions are answered, the confirmed picture remains the one reported on November 1: the mandate has expired, the liquidation phase has begun, and a mission that operated for 35 years is now winding down without a successor arrangement in place.
