During Sudan's civil war, which erupted in April 2023, both sides have increasingly relied on drones, and civilians have borne the brunt of the carnage. The conflict between the Sudanese armed forces (SAF) and the Rapid Support Forces (RSF) paramilitary group is an example of war transformed by commercially available, easily concealable unmanned aerial vehicles (UAVs), or drones. Modular, well-adapted to sanctions evasions and devastatingly effective, drones have killed scores of civilians, crippled infrastructure and plunged Sudanese cities into darkness. In this visual investigation, Al Jazeera examines the history of drone warfare in Sudan, the types of drones used by the warring sides, how they are sourced, where the attacks have occurred and the human toll. The RSF traces its origins to what at the time was a government-linked militia known as the Janjaweed.

The paramilitary Rapid Support Forces (RSF) has killed 27 people in a reported drone attack on a Sudanese army base in the southeastern city of Sinja, a military source told Al Jazeera. Monday's attack coincided with an announcement a day prior that the government, aligned with the Sudanese Armed Forces (SAF), would be returning to the capital, Khartoum, three years after it had shifted its base of operations to Port Sudan. The military source, who spoke to Al Jazeera on condition of anonymity, said Monday's drone attack targeted not only leaders in the government forces but also the security teams and civilians accompanying them. It was unclear how many people were wounded in the attack. Al Jazeera received reports that 13 people were injured, while some estimates have put the number much higher.

The Sudanese armed forces (SAF) are renewing efforts for an operation to retake the Kordofan and Darfur regions from the control of the paramilitary Rapid Support Forces (RSF), as the civil war rages deep into its third year. The army has been assessing the RSF's capabilities and resources in readiness for launching the military operation with a large number of military formations fully prepared to launch an attack, it said. Reporting from Khartoum, Al Jazeera's Hiba Moran said the Sudanese army had reorganised and redeployed troops in various part of Kordofan. "We have also seen the Sudanese army retake control of territories in the Kordofan region as well as launch air strikes and drone strikes on several RSF positions in Darfur and Kordofan," she said. "And it looks like these are the preparations or the first steps of that offensive that the army has been speaking about in efforts to regain control of territories in Kordofan and Darfur," she added.

Major cities across Sudan, including the capital, Khartoum, and coastal city Port Sudan, have been plunged into darkness after drone strikes hit a key power plant in the country's east. Flames and smoke rose from the facility in Atbara, River Nile state on Thursday, which is controlled by the government-aligned Sudanese Armed Forces (SAF) and under attack by the paramilitary Rapid Support Forces (RSF) in the ongoing civil war that has ripped the nation apart. Sudan's RSF trying to hide atrocities: Report Two civil defence members were killed, power plant officials said, while trying to extinguish the fire that erupted after the first strike, adding that rescue workers were injured when a second drone hit as they battled the flames. Al Jazeera correspondent Mohamed Vall in Port Sudan reported that residents initially thought a routine power cut had occurred, only to learn it was linked to incidents in Atbara, roughly 320km (about 230 miles) north of Khartoum. He added that such strikes have become a frequent occurrence in Sudan's war.

Sudanese refugee children watch the sunset in the Tine transit camp amid the conflict between the paramilitary Rapid Support Forces (RSF) and the Sudanese Army, in eastern Chad on Nov. 23. Port Sudan, Sudan - A recent paramilitary drone attack on the army-held town of Kalogi in Sudan's South Kordofan state hit a kindergarten and a hospital, killing dozens of civilians including children, a local official said Sunday. The attack, which took place on Thursday, involved three strikes, first a kindergarten, then a hospital and a third time as people tried to rescue the children, Essam al-Din al-Sayed, head of the Kalogi administrative unit, said using a Starlink satellite internet connection. He blamed the assault on the Rapid Support Forces and their ally, the Sudan People's Liberation Movement-North faction (SPLM-N) led by Abdelaziz al-Hilu, which controls much of South Kordofan and parts of Blue Nile state. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

Drone attack in Sudan threatens Khartoum airport's reopening: Reports A series of drone attacks has hit areas in Sudan's capital, including near Khartoum international airport, a day before its long-awaited reopening, according to the AFP news agency and Sudanese media reports. Witnesses told AFP they heard drones over central and southern Khartoum early on Tuesday. A wave of explosions was reported near the airport between 4am and 6am (02:00-04:00 GMT). The airport has been shut since fighting erupted in April 2023 between the Sudanese army and the paramilitary Rapid Support Forces (RSF), badly damaging infrastructure. Sudan's Rakoba News, citing witnesses, reported more than eight blasts in and around the airport.

The RSF is trying to show that they don't need to reach Port Sudan by land in order to be able to have an impact there,

On May 4, Sudan's paramilitary Rapid Support Forces (RSF) launched a barrage of suicide drones at Port Sudan, the army's de facto wartime capital on the Red Sea. The Sudanese Armed Forces (SAF) accused foreign actors of supporting the RSF's attacks and even threatened to sever ties with one of its biggest trading partners. The RSF surprised many with the strikes. It had used drones before, but never hit targets as far away as Port Sudan, which used to be a haven, until last week. "The strikes … led to a huge displacement from the city. Many people left Port Sudan," Aza Aera, a local relief worker, told Al Jazeera.

Explosions have been heard at the Port of Sudan, a critical lifeline and entry point for aid, as attacks on the city continued for a fourth day in the latest confrontation between Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF) in the country's brutal two-year civil war. The attacks have been blamed on the RSF by Sudan's army and by residents. On Wednesday morning, an army source told the AFP news agency on condition of anonymity that the explosion was due to a drone attack that was met with "anti-aircraft missiles". The Port of Sudan on the Red Sea coast had been a haven city hosting hundreds of thousands of displaced people since the war began and serves as an interim seat for Sudan's military-allied government, which has been at war with the RSF since 2023. The attacks on Port Sudan have increased fears of disruptions to desperately needed aid deliveries in the country suffering one of the world's most dire humanitarian crises, and where famine has been declared in some areas.

Multiple explosions have been heard and a huge fire seen in Port Sudan, though the exact locations and causes were unclear, as Sudan's civil war rocks the previously quiet city for the third day. Dark plumes of smoke could be seen emerging from the vicinity of the country's main maritime port in the city, where hundreds of thousands of displaced people have sought refuge. Al Jazeera's Hiba Morgan, reporting from the Sudanese capital, Khartoum, said residents in the port city reported that attack drones launched by the paramilitary Rapid Support Forces (RSF) hit a fuel depot and other targets. "According to the residents, they believe that it was drone strikes by the paramilitary Rapid Support Forces – once again. They targeted a fuel depot in the city but also around the port and the air base," Morgan said.
