UN peacekeeping mission in Western Sahara ends after 35 years

UN peacekeeping mission in Western Sahara ends after 35 years

Force in Play

The UN has begun dismantling MINURSO and put Alexander Ivanko in charge, while Polisario warns the fighting could escalate and Mauritania clears its border.

4 days ago: Polisario warns of escalation without UN monitors

Overview

Updated 2 days ago

The United Nations has started dismantling its Western Sahara mission and named a former envoy, Alexander Ivanko, to run the withdrawal. About 160 military observers and 180 civilian staff are being sent home, and 13 facilities are closing.

Polisario's foreign minister, Mohamed Yeslem Beissat, said the Russian veto kept the legal case for self-determination alive, and warned the conflict could escalate without UN observers. Morocco says its voluntary ceasefire commitment is unchanged. Mauritania has told people near the border to move away, and the General Assembly debates the vetoes on 10 November.

Why it matters

With no UN observers left, drone strikes and skirmishes along a 2,700-kilometre sand wall can no longer be independently verified.

Scenarios

1

Security Council approves a short technical extension

Possible Resolves by Q1 2027

Discussed by: African Security Analysis, which called a narrowly framed arrangement the most plausible immediate response

After the vetoes, the likeliest diplomatic move is a short extension that separates the mission's continuity from the dispute over autonomy and self-determination. That would restore observers and mine-action support without settling sovereignty. As of 3 November, no such compromise had been adopted; the General Assembly will debate the vetoes on 10 November.

2

Monitoring vacuum persists as low-intensity fighting continues

Likely Resolves by Oct 31, 2027

Discussed by: African Security Analysis and former MINURSO officials quoted by El País

Without observers, incidents along the 2,700-kilometre sand wall become harder to verify. The Secretary-General has warned of escalation. A weaker monitoring environment could let local incidents go unrecorded or be exploited politically.

3

De Mistura brokers a renewed political framework

Unlikely Resolves by End of 2027

Discussed by: UN officials, who say mediation continues through the personal envoy

The UN says it will keep working through Staffan de Mistura. A joint framework would require Morocco and the Polisario Front to agree on talks that do not prejudge sovereignty. Neither side has accepted such terms in three decades of negotiation.

4

A buffer-zone incident pulls Morocco and Polisario into wider fighting

Possible Resolves by Nov 9, 2027

Discussed by: Riccardo Fabiani, North Africa project director at the International Crisis Group

With no UN observers in the buffer zone, a local clash could go unchecked and draw a larger response. Fabiani told Middle East Eye that Rabat might move into the buffer zone while Polisario strikes Moroccan bases from Algerian territory, a scenario he said MINURSO's disappearance makes more plausible.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2000-2008

UNMEE in Eritrea and Ethiopia (2008)

The UN Mission in Ethiopia and Eritrea monitored a contested border after a 2000 peace deal. Eritrea restricted fuel supplies and troop movement, and the Security Council ended the mission in July 2008.

Then

The border stayed tense with no UN observers in place.

Now

The two countries remained in a frozen standoff until a 2018 peace agreement.

Why this matters now

Shows what a monitoring vacuum looks like when a mission ends without a political settlement.

1988-1991

The 1991 Settlement Plan

Morocco and the Polisario Front accepted UN proposals for a ceasefire and a referendum in which Sahrawis would choose independence or integration with Morocco. The Security Council created MINURSO in April 1991 to carry it out.

Then

A ceasefire took hold, but disputes over voter identification stalled the referendum.

Now

MINURSO spent three decades as a monitoring mission rather than a referendum organizer.

Why this matters now

The mandate that just expired was built for a vote that was never held.

October 1975

ICJ advisory opinion on Western Sahara (1975)

The International Court of Justice found no ties of territorial sovereignty between Western Sahara and Morocco or Mauritania. Days later, Morocco launched the Green March as Spain prepared to withdraw.

Then

Spain withdrew, and Morocco took control of most of the territory.

Now

The Polisario Front declared a Sahrawi Republic and fought a guerrilla war until the 1991 ceasefire.

Why this matters now

The legal question was answered in 1975; the political one has not been.
