Western Sahara
Dispute

Western Sahara was partitioned between Morocco and Mauritania in April 1976, with Morocco acquiring the northern two-thirds of the territory. When Mauritania, under pressure from Polisario guerrillas, abandoned all claims to its portion in August 1979, Morocco moved to occupy that sector shortly thereafter and has since asserted administrative control over the whole territory. The official Moroccan government name for Western Sahara is the "Southern Provinces", consisting of the Río de Oro and Saguia el-Hamra regions.

The portion not under the control of the Moroccan government is the area that lies between the border wall and the actual border with Algeria. The Polisario Front claims to run this as the Free Zone on behalf of the SADR. The area is patrolled by Polisario forces, and access is restricted, even among Sahrawis, due to the harsh climate of the Sahara, the military conflict and the abundance of land mines. Landmine Action UK undertook preliminary survey work by visiting the Polisario-controlled area of Western Sahara in October 2005 and February–March 2006. A field assessment in the vicinity of Bir Lahlou, Tifariti and the berms revealed that the densest concentrations of mines are in front of the berms. Mines were laid in zigzags up to one meter apart, and in some parts of the berms, there are three rows of mines. There are also berms in the Moroccan-controlled zone, around Dakhla and stretching from Boujdour, including Smara on the Moroccan border. Mine-laying was not restricted to the vicinity of the berms though, as occupied settlements throughout the Polisario-controlled areas, such as Bir Lahlou and Tifariti, are ringed by mines laid by Moroccan forces.

Despite this, the area is traveled and inhabited by many Sahrawi nomads from the Tindouf refugee camps of Algeria and the Sahrawi communities in Mauritania. United Nations MINURSO forces are also present in the area. The UN forces oversee the cease-fire between Polisario and Morocco agreed upon in the 1991 Settlement Plan.

The Polisario forces (of the Sahrawi People's Liberation Army (SPLA)) in the area are divided into seven "military regions", each controlled by a top commander reporting to the President of the Polisario proclaimed Sahrawi Arab Democratic Republic. The total size of the Polisario's guerrilla army present in this area is unknown, but it is believed to number a few thousand men, despite many combatants being demobilized due to the cease-fire.

Major Sahrawi political events, such as Polisario congresses and sessions of the Sahrawi National Council (the SADR parliament in exile) are held in the Free Zone (especially in Tifariti and Bir Lehlou), since it is politically and symbolically important to conduct political affairs on Sahrawi territory. In 2005, MINURSO lodged a complaint to the Security Council of the United Nations for "military maneuvers with real fire which extends to restricted areas" by Morocco. A concentration of forces for the commemoration of the Saharawi Republic's 30th anniversary were subject to condemnation by the United Nations, as it was considered an example of a cease-fire violation to bring such a large force concentration into the area. In late 2009, Moroccan troops performed military maneuvers near Umm Dreiga, in the exclusion zone, violating the cease-fire. Both parties have been accused of such violations by the UN, but to date there has been no serious hostile action from either side since 1991.

UN sponsored peace talks, the first in six years between Morocco and Polisario, were held in Geneva on 5 December 2018, with both sides agreeing to meet again in a few months for further talks.

During the joint Moroccan–Mauritanian control of the area, the Mauritanian-controlled part, roughly corresponding to Saquia el-Hamra, was known as Tiris al-Gharbiyya.
