Russia and US veto rival UN resolutions on Western Sahara, leaving peacekeeping mission without mandate

On October 30, 2026, the UN Security Council failed to renew the mandate for MINURSO, the 35-year-old peacekeeping mission in Western Sahara. Russia vetoed a U.S.-drafted resolution endorsing Moroccan sovereignty, while a rival Russian draft failed to gather sufficient votes. Consequently, MINURSO's mandate expired on October 31, 2026. Morocco welcomed the decision and called for the departure of UN personnel, while the Algeria-backed Polisario Front warned of escalating regional instability.

Security Council veto standoff

• ▪Russia vetoed a U.S.-drafted UN Security Council resolution that would have supported Moroccan sovereignty over Western Sahara and altered the peacekeeping mission
• ▪A rival Russian-drafted resolution to extend the UN peacekeeping mission in Western Sahara failed

MINURSO mandate expiration

• ▪The mandate for the UN Mission for the Referendum in Western Sahara (MINURSO) expired on October 31, 2026 without a renewed agreement from the UN Security Council
• ▪The defeat of both the US-drafted and Russian-drafted resolutions left MINURSO without a mandate, marking an unprecedented standoff after 35 years of continuous UN peacekeeping operations in Western Sahara
• ▪MINURSO was established by the UN in 1991 to monitor a ceasefire and prepare a referendum on self-determination that was never held due to voter eligibility disputes

US support Morocco autonomy

• ▪The defeated U.S.-drafted resolution, vetoed by Russia, would have formally designated genuine autonomy under Moroccan sovereignty as the only feasible solution to the Western Sahara dispute
• ▪U.S. Ambassador Michael Waltz stated that a Western Sahara referendum had not taken place in 30 years
