Sudan's army has denied it carried out a deadly attack on a major hospital on Friday night in a city in the west of the country held by its rivals, the paramilitary Rapid Support Forces (RSF). The head of the World Health Organization (WHO) said 64 people - including 13 children, two nurses and a doctor - had died in the strike on el-Daein Teaching Hospital and 89 others had been wounded. Enough blood has been spilled, Tedros Adhanom Ghebreyesus posted on X, urging the warring parties to end the conflict, which started nearly three years ago. The RSF said an army drone had hit the hospital in el-Daein, the capital of East Darfur state, on the day Muslims were marking the festival of Eid. Sudan was plunged into a civil war in April 2023 when a vicious struggle for power broke out between the military and the RSF, who had once been allies after coming to power in a coup in 2021.

A drone attack launched from Sudan has killed 17 people in Chad, according to the Chadian government, which has pledged to retaliate against any further strikes as the civil war in the neighbouring nation rages on. A spokesman for the Chadian government announced the death toll on Thursday from the attack on the border town of Tine, which had been targeted despite "various firm warnings addressed to the different belligerents in the Sudan conflict and the closure of the border". Local government sources said it was not immediately clear who was behind the attack, according to Reuters. Chadian President Mahamat Idriss Deby called a meeting of the defence and security council on Wednesday night, ordering the army to "retaliate starting from tonight to any attack coming from Sudan", according to a presidency statement. Early on Thursday, the government said Chad had strengthened its security presence at the border and could potentially carry out operations on Sudanese territory.

Three aid workers killed, 4 wounded in RSF drone attack in Sudan's Kordofan At least three aid workers have been killed and four others wounded in a drone attack by the paramilitary Rapid Support Forces (RSF) on an aid convoy in Sudan's South Kordofan state, according to the Sudan Doctors Network, in the latest carnage against civilians caught up in the nation's brutal civil war. The convoy of trucks carrying food and humanitarian supplies was targeted by the RSF, and its ally, the Sudan People's Liberation Movement-North, while travelling through the Kartala area on its way to the cities of Kadugli and Dilling on Thursday. The network said that this attack marked the "second such incident in less than a month, following the shelling of a United Nations aid convoy in the town of Al-Rahad," adding: "this dangerous escalation threatens the safety of humanitarian operations and further exacerbates civilian suffering". The Sudan Doctors Network reiterated its call to the "international community, the United Nations, and human rights organisations to exert urgent and effective pressure on the leadership of the Rapid Support Forces to ensure the protection of aid convoys and their workers, to open safe and sustainable humanitarian corridors, and to hold those responsible for targeting aid accountable". Al Jazeera could not independently verify the latest RSF attack, which came a month after the government-aligned Sudanese Armed Forces (SAF) announced that it had broken a nearly two-year-long RSF siege on Dilling.

War in Sudan: Life returns to South Kordofan's Dilling but drones keep residents in fear Drone-fired missiles have hit a market in central Sudan's Kordofan region, killing at least 28 people and wounding dozens of others, a rights group says. Emergency Lawyers, a group tracking violence against civilians, said in a statement on Monday that drones bombed the al-Safiya market in the town of Sodari in North Kordofan state. "The attack occurred when the market was bustling with civilians, including women, children and the elderly," the group said. "The repeated use of drones to target populated areas shows a grave disregard for civilian lives and signals an escalation that threatens what remains of daily life in the province. Therefore, we demand an immediate halt to drone attacks by both sides of the conflict," the statement said.

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.

Dozens killed in RSF drone attack in war-torn Sudan's South Kordofan Dozens of people have been killed in a drone attack by the paramilitary Rapid Support Forces (RSF) on a key town in war-torn Sudan's South Kordofan state, according to local media reports. Multiple areas of Dilling, including the headquarters of the Sudanese army's 54th Brigade and the central market, were struck by suicide drones during Wednesday's attack, the Sudan Tribune reported, citing local sources and medical groups. Dilling lies halfway between Kadugli - the besieged state capital - and el-Obeid, the capital of neighbouring North Kordofan province, which the RSF has sought to encircle. The RSF and the SAF have been waging a brutal civil war for control of Sudan since April 2023, which has killed thousands of people and displaced millions. Since the siege was lifted, Dilling has endured a wave of drone attacks that have destroyed service facilities and caused several casualties.

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.

Drone attacks kill over 100 civilians across war-torn Sudan's Kordofan At least 104 civilians have been killed in drone attacks across Sudan's Kordofan region as fighting between rival military factions reached deadly new heights in the brutal civil war deep into its third year. The attacks have battered the central region since early December, right up to Friday, following the capture of a significant army base by the paramilitary Rapid Support Forces (RSF) in Babnusa after a week of intense fighting. Sudan's RSF trying to hide atrocities: Report The deadliest attack was reported from a kindergarten and a hospital in Kalogi, South Kordofan, where 89 people were killed, including 43 children and eight women. United Nations human rights chief Volker Turk said he was "alarmed by the further intensification in hostilities" and warned that targeting medical facilities violates international humanitarian law. Six Bangladeshi peacekeepers serving with the UN mission were killed when drones hit their base in Kadugli, South Kordofan's capital, on December 13.

Sudan's air force has carried out bombings in which at least 1,700 civilians have died in attacks on residential neighbourhoods, markets, schools and camps for displaced people, according to an investigation into air raids in the country's civil war. The Sudan Witness Project says it has compiled the largest known dataset of military airstrikes in the conflict, which began in April 2023. Its analysis indicates that the air force has used unguided bombs in populated areas. The data focuses on attacks by warplanes, which only the Sudanese Armed Forces (SAF) is capable of operating. Its rival, the paramilitary Rapid Support Forces (RSF) does not have aircraft.

A drone attack on the town of Kalogi, in Sudan's South Kordofan region, is said to have hit a kindergarten and killed at least 50 people, including 33 children. The Rapid Support Forces (RSF), the paramilitary group battling the army in Sudan's civil war, was accused of Thursday's attack by a medical organisation, the Sudan Doctors' Network, and the army. There was no immediate comment from the RSF. The RSF in turn accused the army of hitting a market on Friday in a drone attack in the Darfur region, on a fuel depot at the Adre border crossing with Chad. Sudan has been ravaged by war since April 2023 when a power struggle broke out between the RSF and the army, who were formerly allies .
