The Humanitarian Research Lab (HRL) said its analysis of satellite imagery and open-source data showed activity “consistent with military assistance” to the RSF at a base in Asosa, in Ethiopia’s Benishangul-Gumuz region, between late December 2025 and late March 2026.The RSF has been engaged in a conflict with Sudan’s army since April 2023.

Sudan’s military had previously accused Ethiopia of allowing drone attacks to be launched from its territory, an allegation Addis Ababa has denied, along with claims it hosts RSF camps.

According to the HRL report, researchers identified repeated arrivals of commercial car carriers at the Asosa base unloading “technicals,” light pickup trucks commonly used by armed groups.

These vehicles were later observed supplying RSF units operating in Sudan’s Blue Nile state.The report said some vehicles were subsequently fitted with mounts capable of carrying heavy machine guns, while objects consistent with .50-calibre weapons were also detected nearby.

Similar vehicles later appeared in open-source imagery from fighting around Al-Kurmuk, a strategic border town approximately 100 km from Asosa.HRL also documented increased logistical activity at the base, including the arrival of shipping containers, fuel tanks and tents capable of housing up to 150 personnel.

Satellite imagery showed expansion at Asosa airport, including a new hangar, concrete pad and defensive positions. The site had previously been used as a drone base.

The findings come as fighting intensifies in Blue Nile state, where an estimated 28,000 people have been displaced this year, including more than 10,000 from Al-Kurmuk alone.

Control of the region remains divided between Sudan’s army and RSF-aligned forces from the Sudan People’s Liberation Movement-North, led by Abdelaziz al-Hilu.

The strike, which occurred on Wednesday, targeted the Al-Salama neighborhood near a girls’ school, according to the El-Fasher Resistance Committee.

The group attributed the attack to the Sudanese army, which has been engaged in a conflict with the Rapid Support Forces since April 2023.

A medical source said the victims brought to a local hospital included six children, among them three secondary school students.

Sixteen others were wounded in the attack, including women and children, and are receiving treatment.

The strike underscores the continuing toll of the conflict in Sudan’s Darfur region, where fighting between the army and paramilitary forces has displaced large numbers of civilians and strained already limited medical resources.
