UN Western Sahara Mission Ends After 35 Years as Russia Vetoes US Resolution

The United Nations Mission for the Referendum in Western Sahara (MINURSO) entered its liquidation phase on November 1, 2026, after its mandate expired at midnight the previous day. The Security Council could not agree on a renewal following a Russian veto of a United States draft and the failure of a rival Russian text.

Secretary-General António Guterres stated that the mission’s departure does not cancel the people of Western Sahara’s inalienable right to self-determination. He called on all parties to respect and promote those rights. The UN will continue political efforts through Personal Envoy Staffan de Mistura. A smaller team under the Department of Operational Support will return troop-contributing countries’ assets and dispose of UN-owned equipment.

MINURSO was established in 1991 after a ceasefire between Morocco and the Polisario Front. Its tasks included monitoring the ceasefire and preparing a referendum on the territory’s status. The referendum never took place because of disagreements over voter eligibility. Morocco controls most of the territory and has long sought international recognition of its sovereignty claim. The Polisario Front, backed by Algeria, continues to seek independence for the former Spanish colony.

In the Council vote, the US draft received 11 votes in favor, one against (Russia), and three abstentions. The Russian draft received three votes in favor (China, Russia, Somalia), one against (United States), and 11 abstentions. The US text would have affirmed Morocco’s autonomy plan as the most feasible solution and scaled back the peacekeeping presence. Russia opposed language it viewed as endorsing Moroccan sovereignty without broader agreement.

Morocco welcomed the end of the mission. The Polisario Front called the outcome unacceptable. Hostilities have continued at a low level despite the 1991 ceasefire, with occasional flare-ups along the berm that separates Moroccan-controlled areas from the narrow strip held by the Polisario. The territory is roughly the size of Colorado and holds phosphate reserves and fisheries along the Atlantic coast.

The mission’s end removes the only permanent international presence tasked with ceasefire observation. Local commanders and the two sides will now handle incident reporting without UN military observers. Guterres noted the central role MINURSO played for 35 years in limiting escalation and creating space for political talks. Those talks have produced no final agreement.

Last year the Council adopted a US-drafted resolution that described Morocco’s autonomy plan as the most feasible path. Russia abstained then. This year’s veto prevented any extension. The liquidation process is expected to take months as equipment is inventoried and personnel withdraw. Whether the absence of observers increases the risk of larger clashes remains an open operational question for the parties on the ground.
