Russia Veto Ends UN Peacekeeping Mission in Western Sahara

The United Nations peacekeeping mission in Western Sahara has ended after Russia blocked a US-backed proposal to extend its mandate, deepening divisions over the disputed territory. The Security Council failed to approve either a US or Russian resolution on Friday, October 30, 2026, leaving the decades-old conflict without its established monitoring mission.

The United Nations Mission for the Referendum in Western Sahara (MINURSO), established in 1991, was responsible for monitoring a ceasefire between Morocco and the Polisario Front and preparing a referendum on the territory's political future. Its mandate expired on Saturday, October 31.

The US proposal sought a one-year extension while removing "referendum" from the mission's name and making Morocco's autonomy proposal the principal framework for further negotiations. Eleven of the Security Council's 15 members supported the draft, but Russia used its veto.

US Ambassador Mike Waltz criticized Moscow's decision, saying the veto was used to "preserve the letter R (in the Mission’s name) for referendum". He argued that Washington's proposal "would have moved the 50-year conflict forward" and maintained that the existing situation could not continue.

Russia's UN ambassador, Vassily Nebenzia, defended the decision by arguing that the American proposal favored Morocco and prejudged the territory's political status.

"The Security Council cannot automatically predetermine matters relating to sovereignty," Nebenzia said.

Moscow subsequently introduced an alternative resolution seeking to extend MINURSO's existing mandate without the proposed changes. However, the Russian text received only two votes in favor, one against and 11 abstentions, falling short of the nine votes required for adoption.

Nebenzia described Russia's decision to block the American proposal as "a life-saving veto, so to speak".

Morocco welcomed the outcome, with its royal palace arguing that the failure to renew the mission represented a significant development in the dispute. Rabat also called for UN personnel and equipment to leave the territory in the coming days and said the issue should no longer remain before the Security Council.

During the Security Council meeting, Morocco's UN representative challenged Algeria's involvement in discussions about the territory, referring to the country's diplomatic interventions as "lectures".

"Let these people [in the Western Sahara] go back to Morocco," the Moroccan representative said.

"Let them go home," he added.

Morocco maintains that Western Sahara belongs to its territory and supports an autonomy arrangement under Moroccan sovereignty. Its position is based partly on historical and pre-colonial claims to the region.

Algeria, which supports the Polisario Front and hosts Sahrawi refugees, expressed regret over the mission's termination. Its government criticized the American proposal for favoring Morocco and thanked countries that opposed associating themselves with the proposed resolution.

Algeria's UN representative praised countries "who have chosen not to associate themselves" with what the delegate described as "the very foundation of our organisation" being attacked.

The Algerian representative also highlighted the situation of Sahrawi refugees, arguing that the political dimension of their displacement should not be overlooked.

"The tragedy being endured by the Sahrawi people has oddly been diluted to the concept of refugee populations," the representative said.

The Polisario Front also opposed the American proposal. Sidi Omar, its representative at the United Nations, welcomed Russia's veto, arguing that the draft would undermine the Sahrawi people's right to determine their political future.

UN Secretary-General António Guterres separately reaffirmed the organization's commitment to supporting a negotiated settlement. In a statement delivered by his spokesperson on Sunday, November 1, he stressed that ending MINURSO's operations would not remove the population's internationally recognized right to self-determination.

The statement said the UN "stands ready" to continue supporting diplomatic efforts. It also emphasized that the mission's departure "does not abrogate" the people's "inalienable right to self-determination".

Guterres called on all parties "to respect and promote the rights of the people of Western Sahara." He also expressed his "deepest gratitude" to MINURSO personnel who served throughout the mission's 35-year presence.

The secretary-general specifically recognized Special Representative Alexander Ivanko, who led MINURSO through a "particularly challenging period" following the resumption of hostilities in 2020. He also paid tribute to the 20 mission personnel who died during its operations.

Guterres urged the parties to exercise "maximum restraint" and avoid actions that could increase tensions or threaten regional stability. He confirmed that his Personal Envoy for Western Sahara, Staffan de Mistura, would continue supporting diplomatic efforts.

MINURSO had approximately 200 civilian employees, military observers and staff officers from more than 35 countries when its mandate expired. The mission operated nine team sites, with four west of the berm and five east of it, alongside a liaison office in Tindouf, Algeria.

A liquidation period began on Sunday, during which a smaller team reporting to the UN Department of Operational Support will oversee the disposal of mission equipment. A separate UN report had estimated the mission's annual cost at $62 million for the fiscal year beginning in June and listed 155 military personnel.

The dispute dates to Spain's withdrawal from Western Sahara in 1975. Morocco subsequently asserted control over the territory, while the Algeria-backed Polisario Front proclaimed the Sahrawi Arab Democratic Republic in 1976 and demanded independence through a UN-supervised referendum.

The proposed referendum was part of the 1991 ceasefire arrangement, based on settlement proposals accepted by Morocco and the Polisario Front in 1988. However, disagreements over voter eligibility and the territory's political status prevented the vote from taking place.

Morocco introduced its autonomy proposal in 2007, envisioning local self-government while retaining Moroccan sovereignty. The country also maintains control over valuable phosphate deposits and fishing resources in the territory.

Western Sahara remains the last UN-designated "non-self-governing territory" in Africa. The territory is also affected by continuing tensions, with the Polisario Front announcing a return to armed struggle in 2020 after years of ceasefire.

At least 170,000 Sahrawi people have been displaced to refugee camps around Tindouf, according to the background figures cited in the reporting. Morocco maintains a substantial military presence in the territory, estimated at between 100,000 and 140,000 personnel.

Morocco's position has received diplomatic backing from the United States, particularly after President Donald Trump recognized Moroccan sovereignty over Western Sahara in 2020 during his first presidential term. Meanwhile, the UN's diplomatic process will continue through Staffan de Mistura despite the termination of MINURSO's peacekeeping operations.
