Sudanese Army and RSF fight to control Khartoum and Darfur

The ongoing conflict between the SAF and RSF has led to a concentration of hostilities around strategic locations in Khartoum as well as South and Central Darfur. Both actors have raced to secure key military positions while fortifying defenses since the early stages of the conflict. In August, each side strategically launched offensive operations targeting enemy strongholds. While the RSF managed to take control of substantial portions of Khartoum, Nyala, and Zalingei, the SAF relied on airstrikes that inflicted significant damage on RSF facilities and weapon warehouses. These developments occurred amid a sustained period of clashes contesting the control of bases, bridges, and critical supply routes of both the SAF and RSF in Khartoum and Darfur. Developments have varied across Darfur, with clashes involving ethnic militias and self-defense-driven conflicts, as well as the deployment of armed groups to protect civilians. This report breaks down key trends over the past month, focusing on the battle for strategic strongholds in Khartoum and Darfur and its effect on local communities.

The Battle for Khartoum Batters Civilians

Since August, the Khartoum tri-city metropolitan area has been home to a new round of heavy fighting between the SAF and RSF. This escalation has been particularly concentrated in the residential areas adjacent to the SAF’s Armored Corps base in Khartoum, as well as the neighborhoods of Old Omdurman surrounding the Shambat bridge (see map below). The control of key routes has significantly influenced the dynamics and strategic considerations of both parties in this urban theater. The Shambat bridge, for example, is a key location due to its pivotal role as the sole conduit for RSF’s movement of troops and equipment across the Nile river from Omdurman to Khartoum via Bahri.2 The RSF controls both ends of the Shambat bridge, thus maintaining control over this critical position. Reinforcements for the RSF are predominantly channeled from Darfur and Kordofan regions to Omdurman through the Bara road, given that the alternative route linking Kosti and Jebel Awlia is presently under SAF control.3

If the SAF seized control of Shambat bridge, RSF forces in Omdurman would be isolated from their fellow soldiers in Khartoum and Bahri, losing the ability to bring reinforcements from Darfur and remaining vulnerable to the SAF. The loss of the Shambat bridge could eventually mean that the RSF is doomed to lose the battle for Khartoum. Conversely, if the RSF overtakes the Armored Corps base, SAF forces would likely be unable to advance in Khartoum and their forces would be trapped in their last stronghold, the General Command Headquarters. The relentless pursuit of these regions, seen as potential paradigm-shifting elements by both warring factions, has driven them into heavy conflict, inflicting a dire toll upon civilians.

In Khartoum city, the clashes centered in the neighborhoods around the SAF’s Armored Corps base. Armored Corps cadres are notorious for their involvement in many military coups in Sudan. Major General Nasr al-Din Abd al-Fattah – the current commander who resumed duty shortly before the conflict broke out in April – is an associate of former President Omar al-Bashir and was involved in the coup attempt of September 2021.4 Moreover, most of Sudan’s military coups either included or were spearheaded by officers from the Armored Corps.5 From the beginning of August, the SAF took measures to break the siege on the base, which fell under RSF control at the beginning of the conflict.6 The SAF targeted RSF positions around the base, reportedly succeeding in thwarting RSF attacks. South of the Armored Corps base, the RSF managed to repel SAF’s attacks to breach the siege on the al-Yarmouk Complex – a military weapons factory that the RSF overtook on 8 June – claiming the capturing of dozens of SAF soldiers and destroying tanks and military vehicles.

The fighting intensified on 20 August when the RSF effectively broke through SAF defenses around the Armored Corps base. This marked the first instance of breaching the base since the start of the war. The RSF launched simultaneous multi-front attacks on the SAF from neighborhoods in southwestern Khartoum. However, the SAF managed to repulse RSF forces from the base the same day. The SAF claimed that hundreds of RSF soldiers were killed, and a large number of combat vehicles were destroyed or captured. After the RSF forces broke down the wall on the eastern side of the base, they were able to seize control of that eastern portion the following day. The Armored Corps base, a critical infrastructure for the SAF’s infantry, holds high strategic importance for both sides.7 Its capture would grant the RSF control over the base, as well as a vital Khartoum-Omdurman al-Fitahab bridge, thus bolstering its military power and transport routes and significantly shaping the conflict’s dynamics.

In Omdurman, fighting reached a peak on 8 August, with ACLED recording an estimated 160 fatalities that day – nearly as high as during the entire month of July. In fact, August records the most reported fatalities per event in Omdurman, making it the most lethal month for the region since the war began, and was characterized by reports of widespread airstrikes and intense artillery shelling across all contested areas. On 5 August, the RSF forcefully occupied numerous civilian residences in several neighborhoods in Omdurman to fortify its defense positions. Two days later, both the SAF and RSF issued evacuation orders to the residents of Abu Rouf, a neighborhood near the Shambat bridge – thus designating it as a fully operational military zone.8 The next day, on 8 August, the SAF undertook an offensive operation against RSF troops in Old Omdurman neighborhoods to gain control of the Shambat bridge, attacking from both the southern and northern adjacent areas. SAF units stationed at the Karrari SAF bases attempted a southward advance, culminating in confrontations with RSF forces at key locations in northern Old Omdurman, including the Central Reserve Police Headquarters. Other SAF forces moved northward from the Engineers Corps base towards southern Old Omdurman, where they encountered RSF defenses. The clashes also extended to the western areas of Omdurman, with reported SAF airstrikes in the Libya market. The operation aimed to hinder the RSF’s capacity to effectively fortify its forces using the Shambat bridge.

The consequences of these confrontations have been dire, resulting in over 300 deaths, including at least 20 civilians caught in the crossfire.9 Dozens of people killed during the clashes were reportedly buried in a mass grave located in al-Sarha in Omdurman.10 The fighting continued in the locality during the month of August without any significant territorial shifts. SAF airstrikes remained concentrated on RSF forces stationed in southern and western Omdurman. In response, the RSF has instituted measures like obstructing medical supplies, closing markets, and imposing blockades on civilians residing in these neighborhoods to cut SAF’s access to food and medical supplies.11 The intense clashes within the Khartoum metropolitan area in August underscores the escalating dynamics of the conflict, with both sides fiercely contesting control over critical strategic military bases and routes.

The SAF and RSF Clash Amid Escalating Inter-Ethnic Disputes in Darfur

In the Darfur region, the SAF and RSF continued to clash over the control of key towns, such as Nyala and Zalingei where the SAF retains its bases. The region, and South Darfur in particular, experienced escalating tensions and heightened inter-ethnic violence due to disputes over alleged support to the RSF (see map below). This ongoing struggle for dominance coupled with the inter-ethnic dispute, has had a profound and devastating impact on civilians. Clashes between Arab militias were rarely reported before the conflict between the SAF and RSF; however, these militia groups have since been clashing over inter-ethnic disputes. Some indications suggest that implicit allegiance with either side of the conflict has also impacted the violence.

In South Darfur, the city of Nyala experienced almost daily clashes between the SAF and RSF around the SAF’s 16th Infantry base. On 18 August, the RSF launched a multi-front offensive from four directions on the SAF base, using airstrikes and artillery shelling. The SAF, however, managed to ambush RSF forces around the base and captured many RSF soldiers, as well as over a dozen military vehicles. A few days later, the commander of the SAF’s 16th Infantry Division was assassinated by one of his soldiers inside the base, as he refused to surrender to the RSF.12 Additionally, between 11 to 17 August, the RSF successfully took control of strategic locations in the city, including the Mekkah bridge, the Radio Station, and the Guest House Buildings. Hundreds of civilian casualties were reported, while over 50,000 were displaced from their houses.13

Outside Nyala, a series of clashes between Arab militias in South Darfur drove another round of escalation of violence during the second week of August. Clashes involving the Salamat, Beni Halba, and Habbaniya communities reignited again after a spate of fighting in June, when tensions rose due to a looting incident between the militias in May. Clashes broke out in Kubbum on 7 August and continued for multiple days, expanding to other locations south of the region. Fighting originally began over a looting incident in Kubbum, where a Salamat militia reportedly looted a Beni Halba leader; as of writing this report, the reasons for this attack are still unclear.14 Separately, the Salamat tribe refused to announce its support for the RSF15 amid pledges of allegiance to the RSF from the Beni Halba and other South Darfur communities in July.16 An estimated 120 people were killed in multiple locations during the clashes, while dozens of people were reportedly wounded, and hundreds were displaced.17 Militias also looted the Markondi market and obstructed the road between Nyala and Buram. Notably, both Salamat and Beni Halba militias deployed reinforcements from Khartoum, as many of their members are RSF soldiers. The tensions remained high in the area on 18 August as hundreds of Habbaniyah militiamen mobilized in Buram, while large numbers of Salamat forces mobilized in Nadif. Additionally, a considerable number of Masalist militia elements mobilized in the Greida region, indicating the potential for a renewal of clashes and heightened violence.

Meanwhile, in Central Darfur, the SAF successfully regained control of the capital, Zalingei – which was overtaken by the RSF on 4 August – following a series of strategic advancements. The initial progress of the SAF days earlier allowed it to establish checkpoints in the western part of the city, thereby gaining control over several areas where reports mentioned that the RSF was backed by affiliated militias. The SAF reportedly inflicted significant casualties on the RSF in Zalingei, as it remains the highly contested location of the SAF’s 21st Infantry Division.

Finally, in North Darfur, clashes erupted between the SAF and RSF in multiple locations, including in the vicinity of the Abu Shouk camp and al-Takamul neighborhood in El Fasher, with both sides using artillery shelling and light weaponry. Notably, the Joint Forces of the Juba Peace Agreement signatories, which include the Minni Minnawi faction of the Sudan Liberation Movement/Army (SLM/A), Justice and Equality Movement, and others, intervened on 18 August and clashed with RSF units who broke the ceasefire agreement in the city.18

In the ongoing conflict, Darfur region remains a fiercely contested battleground. The RSF has built a strong support base in Darfur, recruiting fighters among ethnic Arab communities who make a higher income than the average Sudanese soldier.19 Yet, the SAF retains its infantry divisions in Darfur, making the region a high prize for all conflict parties. The struggle for control over this region poses a decisive goal that can determine the nationwide war landscape, underscoring the complex and enduring nature of the conflict’s trajectory.

The intensification of hostilities around critical strategic locations in Khartoum and South and Central Darfur has inflicted severe and enduring suffering upon the local civilian populations. The protracted conflict has revealed the vulnerabilities of both the SAF and RSF, raising questions about their ability to secure a decisive victory. Meanwhile, civilians continue to be caught in the crossfire, trapped within the volatile battlegrounds of urban warfare and inter-ethnic violence. As the war continues, various actors are compelled to forge alliances with the warring parties or undertake measures to safeguard their presence in Sudan, illustrating the persistent complexity and instability of the situation.
