Free Zone (region)
The Free Zone or Liberated Territories (Arabic: المنطقة الحرة, romanized: al-minṭaqa al-ḥurra) is a term used by the Polisario Front government of the Sahrawi Arab Democratic Republic, a partially recognized sovereign state in the western Maghreb, to describe the part of Western Sahara that lies to the east of a 2,200-kilometre (1,400 mi) border wall flanked by a minefield, often referred as the Berm, and to the west and north of the borders with Algeria and Mauritania, respectively. It is controlled by the Sahrawi Arab Democratic Republic, as opposed to the area to the west of the Berm, which is occupied by Morocco as part of its Southern Provinces.
