UN Western Sahara Mission MINURSO Lapses After Rival US and Russian Vetoes

The United Nations peacekeeping mission in Western Sahara, MINURSO, has lost its mandate after Russia and the United States vetoed each other’s draft resolutions at the Security Council, ending 35 years of UN monitoring in one of Africa’s longest-running territorial disputes. The mission’s authorisation, last renewed under Resolution 2797, ran until 31 October 2026 and lapsed as 1 November began.

Morocco, which controls most of the territory, welcomed the outcome and said UN personnel and equipment should leave “in the coming days”. The pro-independence Polisario Front, backed by Algeria, also welcomed Russia’s veto of the US text. What happens to the ceasefire, the UN’s staff and the wider peace process is now uncertain.

What Happened at the Security Council?

Two competing drafts were put to a vote on Friday 30 October. According to the UN’s official meeting record, the US draft received 11 votes in favour and three abstentions but was blocked by a Russian veto. A Russian counter-draft, which would have rolled the mission over unchanged until 31 October 2027, received only three votes in favour, from China, Somalia and Russia, with the United States voting against and 11 members abstaining. Some news reports gave a slightly different tally for the Russian draft; we have used the UN’s figures.

The US text would have extended the mission for a year but made Morocco’s autonomy plan the only basis for negotiations, cut the mission’s military component and renamed it MINUSO, dropping the “R” that stands for referendum. Last year the Council backed Morocco’s autonomy proposal as the “most feasible” solution, DW reported, but the US draft would have gone further.

Why Did Russia and the US Block Each Other?

Russia’s ambassador, Vassily Nebenzia, said the US draft favoured one side. “We stress the fact that the Security Council cannot automatically pre-determine matters relating to sovereignty,” he said, according to DW. The UN record quotes the Russian delegation as saying the US text “could have reversed the entire resolution process” for Western Sahara.

The US ambassador, Michael Waltz, said it was unfortunate that “some members of this Council have used their veto to preserve the letter ‘R’ for referendum in the mission’s name, even though the United Nations has not been preparing to hold such a vote for decades”. Washington said it would not keep renewing mandates “year after year for decade after decade” that had not worked.

France warned that an abrupt closure of the mission “would be exceedingly alarming in the context of resumed tensions”, while the UK expressed “immense disappointment” at Russia’s veto. China, which abstained on the US text, said there had been insufficient consultation.

What Was MINURSO’s Role?

MINURSO was set up by Security Council Resolution 690 in 1991 to monitor a ceasefire between Morocco and the Polisario Front and to prepare a referendum in which the people of Western Sahara would choose between independence and integration with Morocco. Disputes over who could vote meant the referendum never took place. Al Jazeera reported that the mission has 155 military personnel and a budget of about $62m for the current financial year.

Western Sahara is a mineral-rich former Spanish colony. Morocco considers it part of its territory, while the Polisario seeks an independent Sahrawi Republic. Tens of thousands of Sahrawis live in Polisario-run refugee camps near Tindouf in Algeria, and low-level fighting has continued since the Polisario said in 2020 that it was resuming its armed struggle.

How Have Morocco, the Polisario and Algeria Reacted?

Morocco’s Royal Cabinet described the failure to renew the mandate as a significant step towards closing the Western Sahara file at the UN. It said the mission’s presence, including its personnel, vehicles, equipment and symbols, should end in the coming days, declaring that a 35-year chapter had closed. Morocco said it remained committed to the ceasefire, according to Al Jazeera.

The Polisario Front’s UN representative, Sidi Omar, thanked Russia for blocking a draft he said “would have undermined the free exercise by the Sahrawi people of their inalienable right to self-determination and independence”. Algeria’s foreign ministry expressed regret on Saturday at the mission’s end and criticised what it called the US draft’s excessive bias towards Morocco.

What Happens to UN Staff Now?

The Moroccan news site Hespress reported that MINURSO had told its personnel in an internal email to park official vehicles, stay away from their workplaces and remain at home until further notice. Hespress noted that this did not by itself mean a withdrawal had begun or that the UN had approved a timetable for departure. The United States has said it will work with the UN Secretary-General on an “orderly and stable drawdown” that protects staff.

The key questions now are whether the ceasefire holds without international monitors, whether the Council returns to the issue, and how the dispute affects relations between Morocco and Algeria. Elsewhere in Africa, MediaPavilion is following the Ebola outbreak in DR Congo and violence in Ethiopia’s Oromia region.
