left Morocco and the Polisario as the sole belligerents in the conflict, which is not yet resolved; a cease-fire has been in effect since 1991. This area is today divided by the Moroccan military berm, with Morocco occupying the parts to the west of it, and the Polisario Front-held Free Zone, under the control of the Sahrawi Arab Democratic Republic to the east. These zones are temporary divisions negotiated as a part of the United Nations Mission for the Referendum in Western Sahara (MINURSO) ceasefire.
