During the 1980s, the Moroccan Wall was constructed north of Tifariti, and the terrain around the town was heavily mined. The risk is greatest east of the Berm, especially in the areas of Mehaires, Tifariti and Bir Lahlou where the Royal Moroccan Army (RMA) conducted offensive operations in August–September 1991. The dangerous result is, among others, scattered cluster bombs, still active in these areas.
