The United Nations ended its 35-year peacekeeping mission in Western Sahara — MINURSO, the Mission for the Referendum in Western Sahara — after Russia vetoed a US resolution to renew it in the Security Council. The mission was established in 1991 to monitor a ceasefire between Morocco and the Polisario Front and to organize a referendum on Western Sahara self-determination that was never held. Thirty-five years after its establishment, MINURSO ends without having fulfilled its core mandate: the referendum never happened, the territory remains under Moroccan administration, and the Polisario Front — backed by Algeria — continues to claim sovereignty. Russia’s veto of the renewal resolution adds a great power dimension to what has been a frozen conflict for decades.

NEW YORK / LAAYOUNE — The United Nations ended its 35-year peacekeeping mission in Western Sahara after Russia vetoed a US resolution to renew MINURSO in the Security Council, according to 10 Things Global News. The specific language of the US resolution that was vetoed, the vote count in the Security Council, whether China also voted against the resolution or abstained, the UN Secretary-General’s reaction to the mission ending, the Moroccan government response, the Polisario Front response, the Algerian government response, whether MINURSO personnel have begun withdrawing, and what monitoring mechanism, if any, replaces MINURSO were not detailed in initial reporting.
MINURSO — the United Nations Mission for the Referendum in Western Sahara — was established by Security Council Resolution 690 in April 1991 following a ceasefire between Morocco and the Polisario Front. The mission was tasked with monitoring the ceasefire and organizing a referendum that would allow the Sahrawi people to choose between independence and integration with Morocco. The referendum was never held due to persistent disagreements over voter eligibility. Morocco controls most of Western Sahara and has administered the territory as its Southern Provinces since withdrawing Spain concluded its colonial administration in 1975. The Polisario Front, backed by Algeria, administers the Sahrawi Arab Democratic Republic from camps in southern Algeria near Tindouf. The conflict has been frozen since the 1991 ceasefire, with occasional Polisario Front military activity resuming in 2020.
Russia Veto and Great Power Dimensions
Russia veto of the MINURSO renewal resolution introduces a geopolitical dimension beyond the Western Sahara conflict itself. Russia has historically supported anti-colonial movements and has maintained diplomatic relations with the Polisario Front and the SADR. However, Russia’s calculation in vetoing a UN peacekeeping mission renewal in 2026 likely reflects a broader strategy of disrupting Western-sponsored international institutions and creating friction with the United States at a moment when Washington is simultaneously engaged in the Ukraine war, Iran nuclear talks, and the Gaza conflict. Morocco itself has been a significant purchaser of Russian military equipment and has maintained a complex diplomatic posture between its Western allies and Moscow. The end of MINURSO after 35 years leaves Western Sahara in a legal and political limbo that benefits Morocco, which has steadily consolidated its administrative control.
“The referendum we were created to organize never happened. The people of Western Sahara deserved better. We depart with sorrow and with the hope that a political solution will still be found.” — MINURSO force commander, departing statement, via 10 Things Global News
