The leader of the Western Sahara’s independence movement has vowed to end a 29-year-old ceasefire with Morocco, citing recent Moroccan border operations as a provocation. Brahim Ghali, leader of the independentist Polisario Front, announced the group will no longer abide by the commitment of the decades-long truce in the area. Morocco, which says it continues to support the ceasefire, announced last week that it would resume military operations in the El Guergarat crossing, a buffer zone between the territory claimed by the state of Morocco and the self-declared Sahrawi Arab Democratic Republic. By launching the operation, Morocco “seriously undermined not only the ceasefire and related military agreements but also any chances of achieving a peaceful and lasting solution to the decolonization question of the Western Sahara,” Ghali said in a letter to the UN. The Western Sahara is a long-disputed territory to the southwest of Morocco controlled mostly by the Moroccan state, which occupies about 75% of the territory, according to the CIA World Factbook.
