Sudan: Over 150 dead after drone attack in Abyei border region

The brief

A drone attack struck a market in Abyei, a disputed area between Sudan and South Sudan. South Sudanese officials later raised the death toll to 153, from an initial estimate of 73. The scale makes it the deadliest attack in Abyei for years. Fires continued after the attack, making it difficult to recover the bodies. Reuters reported that a fuel depot on the market may have been the drone’s target. A diplomat said the Rapid Support Forces had previously used the depot to supply their troops. The attack also displaced about 8,000 people. It adds to wider insecurity caused by Sudan’s war between the RSF and the army, which began in April 2023. Both sides have been accused of attacks in several Sudanese regions, raising fears of further civilian harm and regional instability.

What happened in Abyei, and how many people were killed and displaced?

A drone attack struck a market in Abyei, a disputed area between Sudan and South Sudan. South Sudanese officials later raised the death toll to 153, from an initial estimate of 73. The scale makes it the deadliest attack in Abyei for years.

Fires continued after the attack, making it difficult to recover the bodies. Reuters reported that a fuel depot on the market may have been the drone’s target. A diplomat said the Rapid Support Forces had previously used the depot to supply their troops.

The attack also displaced about 8,000 people. It adds to wider insecurity caused by Sudan’s war between the RSF and the army, which began in April 2023. Both sides have been accused of attacks in several Sudanese regions, raising fears of further civilian harm and regional instability.

02

What is Abyei, and why is it a disputed border region between Sudan and South Sudan?

Abyei is an oil-rich region between Sudan and South Sudan. The two countries jointly administer it, but neither accepts the other’s claim to the territory. That unresolved status makes Abyei more than an ordinary border zone. It is also a place where disputes over land, authority, and resources can become security crises.

The background intensified after South Sudan declared independence in 2011. The new country and Sudan remained connected by the contested region, including its oil wealth. The article also notes that ethnic conflicts occur frequently in Abyei. Those tensions create additional pressure on communities living near the border.

The latest attack was the most serious in Abyei for years. Its location matters because violence there can strain relations between two neighboring states, especially while Sudan is already fighting an internal war. South Sudan’s government blamed Sudan’s army and summoned Sudan’s ambassador.

03

Who are the Rapid Support Forces and the Sudanese Armed Forces, and why are they fighting each other?

The Rapid Support Forces, or RSF, are a paramilitary force. The Sudanese Armed Forces are Sudan’s regular military. They are the two main parties in Sudan’s war, which began in April 2023. Their conflict matters because both command large armed forces and operate across populated areas.

The article links both forces to attacks involving markets and drones. It reports that an RSF-linked fuel depot may have been targeted in Abyei, while the RSF accused the army of shelling a market in South Darfur. The article does not explain the war’s original political dispute. Established background identifies it as a power struggle over control of the state and security forces.

The fighting has spread across Sudan, including Khartum, Darfur, and North Kordofan. Tens of thousands have died, and more than 14 million people have been displaced. Continued rivalry makes civilian protection and accountability especially difficult.

04

Why might a fuel depot used by a military force have been targeted in a marketplace?

A marketplace can become a military target when it contains infrastructure used to support armed forces. Reuters reported that insiders identified a fuel depot as the likely drone target. A diplomat said the RSF had previously used it to supply troops. That alleged military connection may explain why the site was attacked.

Fuel is essential for vehicles, generators, and other military operations. Hitting a depot can therefore disrupt supply lines. But locating such a facility in a market creates exceptional risks. Fire can spread rapidly through fuel and nearby stalls, trapping shoppers and workers. The reported continuing fires made recovery of bodies difficult.

The consequences show why dual-use sites are dangerous in war. Even if attackers intend to strike military supplies, civilians may suffer most. In Abyei, 153 people were reported killed and about 8,000 displaced. The incident also deepened tensions between Sudan and South Sudan.

05

Why do both sides blame each other for drone and market attacks, and how can responsibility for such attacks be established?

Both sides blame each other because the war is contested and accusations can shape public opinion, diplomacy, and military pressure. The RSF blamed the army for a market attack in South Darfur. Local authorities blamed the RSF for an attack in West Darfur. South Sudan’s government blamed Sudan’s army for Abyei.

Attribution requires more than a claim. Investigators can examine drone fragments, explosive remnants, launch locations, flight paths, satellite images, communications, and witness testimony. They can compare these findings with the capabilities and positions of each force. Independent investigators should also check whether evidence has been altered or selectively presented.

The article does not report a confirmed independent conclusion about the Abyei strike. It says both war parties have been held responsible for attacks, while each side denies or redirects blame. Without verified evidence, competing claims remain allegations. That uncertainty can obstruct justice and increase the risk of retaliatory attacks.

06

What are the immediate consequences of the attack for civilians, including fires, displacement, food access, and regional security?

The immediate civilian impact was severe. South Sudanese officials reported 153 deaths, while fires continued at the market and hindered the recovery of bodies. Around 8,000 people were displaced. Families therefore faced loss, possible separation, and the sudden need for shelter and basic supplies.

The market’s fuel depot likely intensified the danger because burning fuel can spread flames quickly. Displacement can also interrupt access to markets, food, water, health care, and income. The article does not give a specific figure for food shortages in Abyei, but it describes Sudan’s war as having created one of the world’s worst humanitarian crises. The WFP is focused on what the country most urgently needs.

Security risks extend beyond the market. Abyei is jointly administered but claimed by both countries. South Sudan summoned Sudan’s ambassador after blaming Sudan’s army. Further accusations or retaliation could worsen border tensions while drone attacks continue elsewhere.

07

How did Sudan’s 2011 split into two countries, oil wealth, and unresolved borders help create the conditions for recurring conflict in Abyei and the wider war?

South Sudan declared independence in 2011, but the separation did not settle Abyei’s status. The region remained jointly administered by Sudan and South Sudan, while both countries continued to claim it. That unresolved border left authority and security contested. The article also identifies Abyei as oil-rich, increasing the importance of controlling it.

These pressures overlap with local ethnic conflict. Communities in Abyei have often faced such tensions, and competing national claims can make local disputes more dangerous. The region’s position between two states also means that an attack can affect diplomatic relations, not only nearby residents.

The wider Sudan war has created another layer of risk. Since April 2023, the RSF and the army have fought across Sudan, causing tens of thousands of deaths and displacing more than 14 million people. The Abyei attack was the region’s worst in years, showing how unresolved borders and national warfare can reinforce each other.
