Clashes between military forces belonging to the Kingdom of Morocco and the self-proclaimed Sahrawi Arab Democratic Republic (SADR), represented at the United Nations by the Polisario Front, broke out in the disputed region of Western Sahara in November 2020. It was the latest escalation of an unresolved conflict over the region, which is largely occupied by Morocco, but 20–25% is administered by the SADR. The violence ended a ceasefire between the opposing sides that had held for 29 years in anticipation of a referendum on self-determination that would have settled the dispute. Despite the establishment of the United Nations Mission for the Referendum in Western Sahara in 1991, the referendum was never held.
Tensions between Morocco and the Polisario Front deepened in mid-October 2020 when Sahrawi peaceful protesters blocked a controversial road connecting Moroccan-occupied Western Sahara to sub-Saharan Africa. The protesters camped on the road near the small village of Guerguerat, which passes through a 5-kilometre-wide buffer strip monitored by the UN. Despite the controversy, the route had grown in economic importance, such that the protest stranded about 200 Moroccan truck drivers on the Mauritanian side of the border. According to the MINURSO, both Morocco and Polisario deployed forces near the area in late October, with Mauritanian forces reinforcing their positions along its border with Western Sahara.
