The United Nations peacekeeping mission in Western Sahara ended operations after 35 years when the Security Council failed to renew its mandate. The closure begins a liquidation phase rather than a political settlement, leaving the territorial dispute and its low-intensity hostilities unresolved.
Russia vetoed a United States draft that supported Morocco's sovereignty claim and would have replaced the referendum-oriented mission with a different political framework. A competing Russian proposal to extend MINURSO for another year then failed to secure the nine votes required for adoption.
A smaller UN support team will oversee the return of national contingents and disposal of equipment. MINURSO had authorisation for 534 personnel, a 2026-2027 budget above $62 million and military contributions led by Egypt, Ghana and Pakistan. Twenty mission personnel died during its existence.
The mission was created in 1991 to monitor a ceasefire between Morocco and the Polisario Front and organise a referendum on self-determination. That vote never occurred because the parties could not agree on voter eligibility, particularly whether to use Spain's colonial census or include additional residents.
Morocco administers most of the former Spanish territory and has made recognition of sovereignty a central foreign-policy objective. The Polisario seeks an independent Sahrawi state from bases and refugee camps in Algeria, which remains its main regional supporter. Morocco welcomed the mission's end; the Polisario and Algeria condemned it.
The security environment is already fragile. The Polisario withdrew from the ceasefire in 2020, and the UN has recorded continuing tensions and low-level conflict. Removing peacekeepers reduces on-the-ground observation and may deepen rivalry between Morocco and Algeria, which severed diplomatic ties in 2021.
MINURSO failed to deliver the referendum in its name, but its presence helped contain escalation and maintained an international stake in the truce. Its departure gives Morocco greater freedom while further isolating the Polisario. The next test is whether diplomacy can replace monitoring before either side seeks advantage through force.
