Free Zone (region)

The Free Zone or Liberated Territories is a term used by the Polisario Front to describe the part of Western Sahara that lies to the east of the Moroccan Berm (the Moroccan border wall) and west and north of the borders with Algeria and Mauritania, respectively. For Morocco, it is a buffer territory.

The area is separated from the rest of the Western Sahara territory by "a 2,200 kilometer [1,367 mi]-long wall...flanked by one of the world's largest minefields." The border is often referred to as the "Berm".

The zone was established as a Polisario-held zone in a 1991 cease-fire between the Polisario Front and Morocco, which had been agreed upon together as part of the Settlement Plan. Morocco controls the areas west of the Berm, including most of the territory's population. The cease-fire is overseen by the United Nations' MINURSO forces, charged with peacekeeping in the area and the organization of a referendum on independence.

The status of Western Sahara is hotly disputed between Polisario and Morocco, and this includes the names used to refer to areas under the control of the different sides.

Morocco routinely refers to the Polisario-held region as a "buffer zone", or "buffer strip", and claims that Polisario forces are not allowed entry, and that both military activities and civilian construction in this area constitute violations of their cease-fire agreement. The Polisario Front, on the other hand, claims this does not correspond to the provisions of the agreement regulating the territory's status, which Morocco signed in 1991, and regards the "buffer strip" as only a slim portion of the entire territory. This zone serves as a division-of-forces no-man's land. Areas outside this zone are open to activity by the side that controls them, provided they adhere to some restrictions on military movements. Similarly, Polisario call the areas a "liberated territory" or the "free zone", but this is not an official designation. The UN calls it simply "east of the Berm", and refers to territories under Moroccan control as "west of the Berm", thus not giving sanction to the claims of either party.
