Russia veto sinks MINURSO renewal, ending 35 years of UN monitoring in Western Sahara

The UN peacekeeping mission in Western Sahara ceased operations on Sunday, November 1, 2026, after 35 years. Its mandate expired at midnight on Saturday, October 31, following the Security Council's failure on Friday, October 30, to agree on its renewal.

A U.S. draft resolution was vetoed by Russia. A rival Russian text then failed to win the nine votes needed for adoption. Neither proposal secured the Council's agreement, and the mission's mandate lapsed.

MINURSO had been in place since 1991, monitoring a ceasefire in a territory roughly the size of Colorado, rich in minerals and fisheries, and claimed by both Morocco and the pro-independence Polisario Front. Its departure removes the primary international mechanism that had been in place for more than three decades.

UN Secretary-General António Guterres said the mission's departure "does not abrogate" the people's "inalienable right to self-determination." He called on all parties to respect and promote the rights of the people of Western Sahara. The UN will continue peace efforts through the Secretary-General's Personal Envoy, Staffan de Mistura.

A liquidation period began November 1. A smaller team reporting to the UN's Department of Operational Support will oversee the orderly transportation of assets belonging to troop-contributing countries and the disposal of UN equipment.

Morocco welcomed the decision. The Algeria-backed Polisario Front expressed concern.

The self-determination question remains unresolved. The end of MINURSO is not a resolution but a vacuum: the ceasefire-monitoring mission expired because the Security Council could not agree, not because peace was achieved. The UN's ability to support a political solution now depends on a smaller diplomatic footprint and on de Mistura's envoy role.
