Clashes between Morocco and the Polisario Front's Sahrawi Arab Democratic Republic (SADR) broke out in the disputed region of Western Sahara in November 2020. It was the latest escalation of an unresolved conflict over the region, of which 75–80% is occupied by Morocco. The violence ended a 1991 ceasefire between the opposing sides that had held for 29 years in anticipation of an indefinitely stalled referendum on self-determination that would have settled the dispute.
Tensions between Morocco and the Polisario Front deepened in mid-October 2020 when peaceful Sahrawi 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. Morocco entered the buffer zone and captured the road in mid-November; the following day, the Polisario Front declared that the 1991 ceasefire was void.
As of 2026, the Polisario Front continues to wage attacks against Morocco. In turn, Morocco has used drones to attack Polisario-controlled territory, killing at least 120 people.
Background
Western Sahara is a sparsely populated area mostly comprising desert territories, situated in the Maghreb region of Africa's northwest coast. The United Nations has designated the area as a non-self-governing territory since 1963; it is also the only African territory on the list, making Western Sahara the last African territory subject to decolonization. The region was a Spanish colony until February 1976, when the Spanish government informed the United Nations that it withdrew from the territory. Since then, the region has been the subject of a long-running territorial dispute between Morocco, supported by a number of its prominent Arab allies, and the Sahrawi Arab Democratic Republic (SADR), an African Union member state established by the Algerian-backed pro-independence Polisario Front, which is recognized by the United Nations as the legitimate representative of the indigenous Sahrawi people. Some commentators have connected Morocco's interests over the region with the irredentist idea of Greater Morocco, which encompasses Western Sahara and areas of neighboring countries.
The Polisario Front was established in May 1973 to wage a low-intensity war of national liberation against Spanish colonial authorities. In October 1975, the International Court of Justice issued an advisory opinion that Morocco and Mauritania possessed no territorial sovereignty over Western Sahara and that the Sahrawis were entitled to the right to self-determination. Weeks later, Moroccan and Mauritanian forces, aided by France, invaded the territory, marking the beginning of the Western Sahara War. While Mauritania withdrew from Western Sahara and recognized the SADR early in the conflict, by the end of the war Morocco had obtained control of more than two-thirds of the vast desert territory in its western part, along the Atlantic Ocean. Morocco built a 2,700 kilometres (1,700 mi)-long sand wall to split the territory. In 1991, Morocco and the Polisario Front agreed to a UN-brokered ceasefire that promised a self-determination referendum to the Sahrawis, to be conducted by the United Nations Mission for the Referendum in Western Sahara (MINURSO). Since then, the referendum has been repeatedly delayed; Morocco had refused the terms of the referendum, citing its dissatisfaction with who was allowed to vote, while tens of thousands of Moroccans have emigrated to the region since the 1970s.
Guerguerat blockade
Guerguerat is a small village located on the southern coast of the region, along the Moroccan National Route 1 leading to Mauritania, some 380 kilometres (240 mi) north of Nouakchott, in a buffer zone patrolled by MINURSO. The Polisario Front considers the road illegal since they say it was built in violation of the ceasefire. Tensions deepened between Morocco and the Polisario Front in mid-October 2020, when unarmed Sahrawi refugees from the Tindouf camps in Algeria passed through SADR-controlled territories to camp on and block the road in protest of what they called the plunder of Western Saharan resources from the Sahrawi people, creating a large caravan of vehicles and blocking traffic in the region.
Morocco, which regards the region as vital to trade with sub-Saharan Africa, accused the Polisario Front of infiltrating the buffer zone and "carrying out acts of banditry" in Guerguerat. The Moroccan authorities also stated that the Polisario Front was harassing UN troops at the crossing, though the UN denied this.
These protesters were later joined by a group of up to 12 Sahrawi People's Liberation Army (SPLA) fighters and 8 light vehicles, two of which had mounted heavy weapons, in violation of the ceasefire. The Polisario Front claimed they were exclusively there to protect the protesters but later removed some of the light vehicles on 29 October after being told by MINURSO to withdraw from the area. At the same time, 16 Royal Moroccan Army vehicles carrying heavy-duty machinery were observed west of the berm near Guerguerat. To reduce tensions, MINURSO requested that the Moroccan army to leave the area. Despite claiming it would comply with the request, no withdrawal was observed.
In early November, around 200 Moroccan truck drivers appealed to Moroccan and Mauritanian authorities for help, saying they were stranded on the Mauritanian side of the border near Guerguerat, and adding that they didn't have access to drinking water, food, shelter, or medicine, with some suffering from chronic illnesses. On 6 November, MINURSO observed Morocco deploying a large force of 250 vehicles near Guerguerat. On 12 November, Mauritanian forces reinforced their positions along border with Polisario Front–controlled territories. The secretary-general of the United Nations, António Guterres, launched numerous initiatives to prevent escalation within the buffer zone, but his efforts had failed.
Course of the conflict
Guerguerat offensive (2020)
On the morning of 13 November, Morocco launched a military operation from the Western Sahara sand wall into the demilitarized buffer strip of Western Sahara to clear the protesters near Guerguerat. MINURSO observed heavy weapons fire from the Moroccan military and two gunshots from the Polisario Front. After clearing out the buffer zone, Morocco entered with bulldozers and began extending the sand wall. The Polisario Front urged the United Nations to intervene, noting that the Moroccan military operation violated the 1991 ceasefire agreement, and accused the Moroccan security forces of shooting at unarmed civilians in the buffer strip. Morocco denied there had been any armed clashes between the sides and said the truce remained in place. No casualties were reported.
Clashes spread that same day along the sand wall, with Morocco claiming that it had repelled a Sahrawi incursion near Al Mahbes. Both Morocco and the SADR introduced mass mobilisation. The SADR evacuated civilians from the Guerguerat area and introduced a curfew in the territories under its control. The following day, it declared that the 1991 ceasefire with Morocco was terminated. 4,700 Sahrawis were displaced by the clashes in late 2020.
Low-intensity clashes (2021–present)
Since the initial Guerguerat crisis, the Sahara Press Service and MINURSO have regularly reported on Polisario Front attacks against Moroccan forces positioned at the sand wall. In October 2021, SADR president Brahim Ghali reiterated that attacks would continue. Initially, Morocco neither confirmed or denied the Polisario Front's attacks, and stated that there was a "total absence of any armed conflict". However, by May 2024, it acknowledged that "ceasefire violations" were ongoing. El Mundo has described the clashes as a "silent war", "away from the world's attention".
Morocco has no ground presence in the Polisario-controlled territories and uses aerial surveillance to identify targets. Morocco began its drone warfare in January 2021; there are no effective defenses in Western Sahara against the drones. Sahrawi civilians' pastoral lifestyle has been disrupted by the constant fear of Moroccan drones. The Polisario Front has accused Morocco of indiscriminate attacks and has documented Morocco's alleged use of thermobaric bombs against civilians. By November 2024, at least 120 people have been killed by Moroccan drones.
Peace talks overseen by US advisor Massad Boulos secretly took place in early 2026, though they never concluded because the United States shifted its priority to the 2026 Iran war. In May 2026, the European Union, France, and the United States denounced a shelling attack by the Polisario Front that injured a Moroccan civilian in Smara—marking the first instance of Western states issuing a condemnation of the clashes. The following month, commander Lehbib Mohamed Abdelaziz, son of former Sahrawi president Mohamed Abdelaziz, was killed in a Moroccan drone attack alongside two other Polisario Front members.
Foreign weapon supplies
Morocco
Following the signing of the Israel–Morocco normalization agreement in December 2020, Morocco has purchased advanced military equipment from Israel including at least 150 drones. The use of these drones has been documented in Polisario-controlled Western Sahara where they have killed both SPLA fighters and civilians. Israeli drones are also suspected to have been used to follow the movements of SPLA forces. In October 2022, Morocco made a deal with Israel to build two factories to produce war drones with Israeli supervision and expertise. These factories, once completed, will allow Morocco to manufacture advanced drones at a low cost compared to those it had been buying from China and Turkey.
Morocco reportedly used a Chinese-made Wing Loong Is, among a few given as a gift from the United Arab Emirates, to kill Addah al-Bendir, the chief of the Polisario's Gendarmerie, in April 2021. Missile fragments examined by the Intercept indicated that Bayraktar TB2 attack drones sold by Turkey have been used on targets in Western Sahara. In 2025, Morocco began using the Turkish-produced Baykar Bayraktar Akinci.
Sahrawi Republic
Since the start of the clashes, Algeria has reiterated its support for Western Saharan independence. However, Algeria has been reluctant to send the SADR any serious type of equipment. Consequently, the SADR has been compelled to rely on outdated equipment dating back to the late 1980s and early 1990s, given that its previous arms supplier, Muammar Gaddafi, was killed in 2011. This predicament poses a challenge for the SPLA forces as they have to confront Moroccan forces equipped with more advanced weaponry, including drones. Despite that, Algeria still cooperates with the SADR by keeping its borders open to their fighters.
Moroccan, Israeli, and Western media have promoted disinformation alleging that the Polisario Front is supported by Iran, Hezbollah, and Ba'athist Syria. The Polisario Front has denied these allegations.
Reactions
Official statements
- Morocco: On 13 November, the Authenticity and Modernity Party, the Party of Progress and Socialism, the Popular Movement Party, and the Independence Party voiced their support for the Moroccan military intervention. The next day, the House of Representatives of Morocco issued a statement, stressing that the military intervention was legitimate. On 16 November, King Mohammed VI stated that Morocco would take necessary measures to "keep order and protect safety and fluidity of passenger and commercial traffic in the border area between Morocco and Mauritania", adding that the UN had failed in its "laudable attempts to end the unacceptable acts of the Polisario". Prime Minister Saadeddine Othmani said the operation led by the Moroccan forces was a "strategic change" to open the route in the Mauritania border.
- Sahrawi Republic: On 16 November, SADR's minister of foreign affairs Mohamed Salem Ould Salek stated that the end of the war was now linked to the "end of the illegal occupation of parts of the territory of the Sahrawi Republic", and that the war had started as a "consequence of Morocco's aggression and action in Guerguerat".
Domestic
On 13 November, Sahrawi sources stated that there were mass protests in Laayoune, the unofficial capital of Western Sahara, which is de facto administered by Morocco, against the clashes. The Moroccan media denied these claims, stating that the city's population was in support of the Moroccan forces, citing Laayoune's mayor. Despite that, the NGO media outlet Équipe Media reported that the Moroccan government was exercising a strong police force, and had arrested several activists. The next day, the same source stated that the Moroccan security forces had arrested several demonstrators in Smara.
