CAIRO — Drone warfare has become the deadliest threat to civilians in Sudan ‘s conflict and both the military and the rival paramilitary Rapid Support Forces are being supplied by a number of countries in the Middle East and beyond, experts say.

“Armed drones have now become by far and away the leading cause of civilian deaths,” or over 80% of conflict-related deaths, United Nations human rights chief Volker Türk said this week, calling for measures to prevent their transfer to Sudan. Drones killed at least 880 civilians between January and April.

The war in Sudan began in April 2023 and has killed at least 59,000 people, displaced some 13 million and pushed parts of the country into famine.

In recent weeks, the RSF has carried out drone attacks on Khartoum International Airport and other areas near the capital, which the army seized control of last year.

Analysts say foreign-supplied advanced drone technology enables the warring parties to expand strikes on densely populated areas, complicating peace efforts and raising fears of a broader proxy conflict.

“On the battlefield, drones have emerged as a force multiplier, enabling ground offensives and weakening enemy defenses,” said Jalale Getachew Birru, East Africa senior analyst at the U.S.-based Armed Conflict Location & Event Data project.

Both the army and RSF use drones to secure contested territory, disrupt mobilization efforts and spread insecurity in areas controlled by rivals, he said.

At least 2,670 people, including combatants and civilians, were killed in 2025, marking a 600% increase in drone-related deaths and an 81% increase in drone attacks compared to the previous year, ACLED found.

Drone strikes by the warring parties have targeted civilian infrastructure including hospitals, dams, schools, markets and displacement camps.

Most of the civilian deaths in drone attacks have occurred in the Kordofan region in the central Sudan, according to Türk.

On May 8, drone strikes in South Kordofan and near the city of el-Obeid in North Kordofan reportedly killed 26 civilians. More than 70 people were killed in drone attacks on densely populated areas in Kordofan earlier this year, according to the Sudan Doctors Network.

On Tuesday, a Sudanese rights group, the Emergency Lawyers, said nine drone attacks on civilian vehicles had killed at least 36 people over the past 10 days across seven provinces.

The group blamed both the army and RSF and said some drones use visual monitoring technology capable of distinguishing targets, raising concerns that the attacks may not have been indiscriminate.

The paramilitary RFS began only last year to use drones widely, said Gabriella Tejeda, research associate at The Soufan Center.

The army and RSF are competing to obtain new drone models, particularly from China, but the RSF is modifying drones and “increasingly competing to acquire newer, more sophisticated models, with the UAE likely supplying them,” Tejeda said. The United Arab Emirates has denied supplying drones to the RSF.

Nathaniel Raymond, executive director of the Humanitarian Research Lab at the Yale School of Public Health, said the RSF is backed by external technology, particularly from the UAE, with satellite imagery showing its use of Chinese-made CH-95 and FH-95 drones that are roughly the size of small aircraft.

In areas such as el-Fasher city in North Darfur, where at least 6,000 people were killed over three days last year, RSF drones shut down communications of civilians “crying for help” and target them where a signal is detected, Raymond said.

The RSF couldn’t have seized the city without these capabilities, he added.

“The sophistication of how they use drones in el-Fasher is unique because it’s the first time you’ve seen this layered, hunter-killer concept of operations to kill people, basically in a kill box or trapped inside a wall, in this case to prevent them from crying for help,” Raymond said of the city, where U.N. experts said the violence indicated “hallmarks of genocide.”

The army’s drone technology has been blamed for striking civilian infrastructure such as Al Daein Teaching Hospital in East Darfur, where at least 64 people were killed. The army officially denied responsibility. Two military officials at the time, however, said the intended target was a nearby police station.

Raymond said there has been an “alarming increase” in army drone strikes on protected infrastructure such as schools and markets in the past four to six months. The army has maintained that it doesn’t target civilian infrastructure.

Last month, ACLED said the army’s drone technology is supplied by Turkey, Russia, Iran and Egypt, while the RSF is supplied via networks linked to the UAE through regional transit points including Ethiopia, Chad and Libya.

Earlier this month, the Sudanese government accused neighboring Ethiopia of being behind recent drone attacks on sites including the Khartoum airport. It accused the UAE of supplying the drones. Both countries denied the allegations.

″Ethiopia is a central partner to the UAE, so the allegations are not unfounded and reflects an attempt by the UAE to try to influence the outcome of the war,” Tejeda said.

Cross-border drone activity may have contributed to rising civilian deaths, but Birru and Raymond said that is difficult to confirm.

“Both the warring parties’ battle tempo only increasing, and their backers actively still investing in the war, makes it clear that neither side is interested in a resolution,” Tejeda said.
