The UN said its 35-year-old peacekeeping mission in Western Sahara had come to an end after the Security Council did not renew its mandate

Efforts by international actors to prevent armed conflict from starting, contain it once underway, and support post-conflict stabilization. Encompasses military deployments, ceasefire monitoring, civilian protection, and political mediation — a central function of multilateral security architecture.

The Security Council failed to renew MINURSO before its mandate expired after Russia vetoed a US draft supporting Morocco's autonomy proposal. Russia's alternative received only three affirmative votes, below the nine required. The failure places ceasefire monitoring in uncertainty but does not itself order the peacekeepers' immediate withdrawal.
