US and Russia clash over Western Sahara as rival UN resolutions fail and peacekeeping mission faces closure
By Sadaf Sundas Riaz — SCN NEWS
UNITED NATIONS — The United Nations Security Council failed on Friday to renew its 35-year peacekeeping mission in Western Sahara after Russia blocked a U.S.-backed proposal supporting Moroccan sovereignty and a competing Russian resolution failed to secure enough votes, leaving the disputed territory without a renewed international monitoring mandate just one day before its expiration. The confrontation exposed deep divisions between Washington and Moscow over the future of the territory, which Morocco largely controls but which the Algeria-backed Polisario Front claims for an independent Sahrawi state. Unless council members reach a last-minute agreement, the mandate of the United Nations Mission for the Referendum in Western Sahara, known as MINURSO, will expire on October 31.
The United States had proposed significant changes to the UN mission and the diplomatic framework governing the dispute, seeking to establish Morocco's autonomy proposal as the principal basis for a political settlement while reducing the mission's military monitoring responsibilities. Russia rejected the American resolution, arguing that it would effectively determine the territory's future sovereignty before negotiations had produced an agreement acceptable to the parties. Moscow subsequently introduced a competing resolution calling for the existing mission to continue for another year, but the proposal received only three votes in favour, one against and 11 abstentions, falling short of the nine affirmative votes required for adoption.
The failure of both proposals represents an unusual breakdown in Security Council diplomacy over a peacekeeping operation whose mandate has been renewed regularly since its establishment in 1991. Although the mission has never achieved its original objective of organising a referendum on Western Sahara's political future, it has continued to monitor security conditions and maintain a UN presence in a territory where the conflict remains unresolved. Its possible termination raises questions about how ceasefire monitoring and communication between the opposing sides would continue without an established international mission.
The American proposal reflected Washington's increasingly explicit support for Morocco's position that Western Sahara should remain under Moroccan sovereignty while receiving a degree of internal autonomy. The draft would have removed the reference to a referendum from the mission's name, replacing MINURSO with the United Nations Mission in Western Sahara, or MINUSO, and established a revised framework for its future operations. The proposed changes would have marked a substantial departure from the mission's original mandate, which was created to support a political process intended to allow the Sahrawi population to determine the territory's future.
U.S. Ambassador to the United Nations Mike Waltz defended Washington's approach, arguing that the referendum envisaged under the original peace agreement had never taken place because of longstanding disagreements over voter eligibility. He said the international community needed to recognise the political circumstances that had prevented the vote from being organised for decades and pursue a more practical settlement. Waltz criticised Russia's decision to block the American resolution, saying it had prevented progress towards resolving a conflict that has remained unsettled for more than half a century.
Russia's UN Ambassador Vassily Nebenzia rejected the suggestion that the Security Council should endorse a political outcome favouring one side before negotiations had concluded. He argued that sovereignty over Western Sahara could not be determined automatically through a resolution that effectively excluded other possible outcomes, including independence. Nebenzia also criticised the failure of Russia's competing proposal, which would have preserved the existing mission and extended its mandate until October 31, 2027, without fundamentally changing the framework established under earlier UN decisions.
Morocco welcomed the failure to renew the peacekeeping mission, describing the outcome as a significant development in its longstanding campaign to secure international recognition of its sovereignty over Western Sahara. In a statement issued by the royal palace, Moroccan authorities said the absence of a renewed mandate meant that UN personnel, vehicles and equipment should leave the territory in the coming days. The palace also argued that the Western Sahara dispute should no longer remain under consideration by the Security Council, although Morocco maintained that it remained committed to the existing ceasefire arrangements.
The Polisario Front, which seeks independence for Western Sahara, welcomed Russia's opposition to the American proposal and accused Washington of attempting to undermine the principle of Sahrawi self-determination. Its representative at the United Nations, Sidi Omar, argued that the proposed changes would have weakened the foundations of the UN peace process by treating Moroccan sovereignty as the predetermined outcome of negotiations. The movement maintained that a lasting settlement must preserve the right of the Sahrawi people to determine their political future, including the possibility of independence.
Western Sahara has remained disputed since Spain withdrew from the territory in 1975, after which Morocco asserted control over much of the region and the Polisario Front launched an armed struggle for independence. The conflict displaced large numbers of Sahrawis, many of whom have lived for decades in refugee camps near Tindouf in neighbouring Algeria, which supports the Polisario movement. A United Nations-brokered ceasefire in 1991 led to the establishment of MINURSO, but the referendum intended to determine the territory's status was repeatedly delayed because Morocco and the Polisario Front could not agree on who should be eligible to participate.
The ceasefire framework came under renewed pressure in November 2020, when the Polisario Front announced that it was resuming armed operations following tensions near the Guerguerat crossing between Western Sahara and Mauritania. Although fighting has remained limited compared with the earlier decades of the conflict, the deterioration in relations has complicated international efforts to restart meaningful political negotiations. The continued presence of UN military observers has provided an independent monitoring mechanism, even as the broader political process has remained stalled.
The mission currently has approximately 155 military personnel, according to UN reporting, and its estimated operating cost for the fiscal year beginning in June 2026 is about $62 million. Its responsibilities have included observing security developments, maintaining contact with the parties and reporting to the Security Council on conditions in the disputed territory. The possible withdrawal of these personnel would remove an established international presence at a time when the underlying political disagreement remains unresolved and the parties continue to hold sharply different positions on sovereignty.
Humanitarian organisations have warned that the disappearance of the mission could increase uncertainty for civilians and refugees affected by the prolonged dispute. Oxfam said the loss of MINURSO's monitoring and de-escalation functions could undermine regional stability and weaken prospects for a peaceful settlement. Tens of thousands of Sahrawi refugees remain dependent on humanitarian assistance in camps in Algeria, where prolonged displacement and limited economic opportunities have compounded the consequences of the unresolved conflict.
The diplomatic confrontation also reflects competing international approaches to Western Sahara, with the United States, France and Britain supporting Morocco's autonomy proposal while Russia and China have continued to emphasise the principle of self-determination. In October 2025, the Security Council adopted a resolution identifying Morocco's autonomy proposal as a basis for negotiations, marking an important shift in the international diplomatic framework. The latest American draft sought to move further by strengthening the preference for autonomy under Moroccan sovereignty, a position that Russia argued would undermine the credibility of negotiations involving the Polisario Front.
The disagreement leaves UN Secretary-General Antonio Guterres and his personal envoy for Western Sahara, Staffan de Mistura, facing a difficult diplomatic situation as the council approaches the expiration of the mission's mandate. Efforts to negotiate a political settlement have involved Morocco, the Polisario Front, Algeria and Mauritania, but the parties have remained divided over the fundamental question of whether Western Sahara should become independent or remain under Moroccan sovereignty. The failure of the rival resolutions means that the Security Council has not established a new framework for the mission's operations or agreed on an alternative international mechanism to replace its monitoring responsibilities.
The immediate consequences will depend on whether Security Council members can reach an agreement before the existing mandate expires on Saturday. Without a renewed authorisation, the United Nations would face the prospect of winding down a mission that has operated for more than three decades, while Morocco and the Polisario Front remain divided over the territory's political future. Friday's votes demonstrated that the major powers have yet to agree on how the dispute should be resolved, leaving the future of international peacekeeping in Western Sahara uncertain at a critical moment for the region.
