On 15 April 2023,
Geneina, the capital of West Darfur, was
largely captured and occupied by RSF forces, with little resistance, except at
Geneina Airport. The occupation of the city lasted until 25 April 2023, when a battle for the city resumed and was reportedly 'deadly'. By the end of the battle, over 200 people had been confirmed to be killed, with the number estimated to be much higher between soldiers and civilians. On 2 May, Geneina was mostly captured by RSF, while the group also kept advancing in several other areas of the province. By 23 April 2023, the
Kabkabiya fell under the control of the RSF. Three employees of the
World Food Programme (WFP) were killed after being caught in the crossfire at a military base. Two other staff members were injured. The RSF quickly began to enlist Darfur's Arab tribes to expand its ranks and gain the upper hand in the area. Together, the RSF and its allies quickly overran large parts and Darfur, and began to expel or outright massacre non-Arabs. According to security analyst Andrew McGregor, the RSF operations in Darfur appeared to aim at "ethnically cleans[ing] the region of its indigenous Black population". In response, several non-Arab militias and ex-rebel groups in Darfur allied with the SAF to defend their holdings. Five major armed groups formed the
Darfur Joint Protection Force; the alliance included the
Justice and Equality Movement (JEM) under
Gibril Ibrahim, the
Sudan Liberation Army faction (SLA-MM) of Darfur Governor
Minni Minawi, and the
Gathering of Sudan Liberation Forces under
al-Tahir Hajar. However, the cooperation between the Sudan Armed Forces and the Joint Protection Force remained difficult, as both sides distrusted each other. Several member groups of the Joint Protection Force experienced internal divisions over the alliance with the SAF, with some factions leaving their respective groups to stay neutral or even side with the RSF.
Siege of Zalingei Between 17 and 23 May 2023, the
Zalingei Teaching Hospital was looted as was the
Médecins Sans Frontières warehouse. Telecommunications were also cut off. By 29 May, Zalingei became a new epicentre of the fighting under siege by armed militias. Housing and infrastructure were destroyed. The town reportedly faced medical shortages after looting and attacks by the
Rapid Support Forces. In June 2023, the
United Nations reported of clashes inside the city. On 6 August 2023, the RSF claimed they had taken full control of the city and the wider Central Darfur region. The SAF subsequently claimed that it had raised the siege of Zalingei and had retaken the western part of the city from the RSF. On 31 August, Zalingei's SAF garrison, consisting of the 21st Infantry Division, fled the settlement. This allowed the RSF to fully secure the entire city without further opposition.
Capture of Ed Daein Tension between the army and the RSF escalated near Ed Daein after the RSF threatened on 16 November to attack the city, send an ultimatum to the army until Sunday to withdraw. This led to many citizens leaving in case of future battles. The RSF also seized the nearby Adila oilfield in East Darfur two months earlier on 11 August 2023. On 20 November, the battles in the city began to start as the RSF launched an offensive on the city. By the 21st, the RSF was able to capture the oilfield of Shag Omar, also known as Sufyan, the RSF also published videos of their seizure of the international airport in Ed Daein. This led the army to retreat eastward. Later on the 21st, the latter captured the 20th Infantry Division base at around 4:00am, according to RSF commander in East Darfur, Hassan Saleh Nahar, which makes the 4th army base in
Darfur to fall to the RSF. All supplies and weaponry were also captured according to the statement. The RSF managed to took over the city by 22 November 2023.
Battle of Nyala and al-Fashir On 26 October, the RSF
captured Nyala, Sudan's second-largest city and South Darfur's capital, after a long siege. As the city had served as a major military center, this was a major victory for the RSF. The center of West Darfur, Geneina, was fully conquered by the RSF on 4 November. In course of and after the battle for Geneina, the RSF and its allies subsequently massacred many civilians. The fall of Geneina caused many SAF garrisons in Darfur to also abandon their posts and desert or flee to
Chad. Meanwhile, the RSF and its allies laid
siege to al-Fashir, the capital of the entire Darfur region. At al-Fashir, the SAF-Joint Protection Force garrison received support by another rebel group, the Sudan Liberation Army's al-Nur faction (SLA-AW). By mid-December 2023, McGregor assessed that the RSF was nearing victory in the conflict over Darfur, controlling four of the region's five states. Al-Fashir still remained under control of the Joint Protection Force, but it was no longer receiving supplies from the SAF-held areas in central Sudan, causing food, fuel, and medicines shortages. Meanwhile, SAF control was also collapsing in other parts of Sudan, making any additional support for the Darfuri holdouts more unlikely. By May 2024, al-Fashir had become the last stronghold of the Sudanese government in Darfur. The city remained besieged by the RSF which had begun to launch raids into the settlement. On 26 October 2025, El Fasher fell to the RSF after numerous assaults in previous months, resulting in widespread massacres and an ongoing refugee crisis. In April 2026, an RSF commander and one of the founders of the militia, known as Al-Qubba, who served in the seizure of El Fasher, had defected to the Sudanese army. The defection was due to disagreements with the RSF on not giving Al-Qubba the lead of the RSF command in North darfur. His defection has been welcomed by the Sudanese president
Abdel Fattah al-Burhan himself in
Northern Sate. RSF has sentenced him to death in absentia. == Foreign role in the campaign ==
