A report by a group of researchers at Yale University, released on Wednesday, revealed that an Ethiopian military base near the Sudanese border is supporting the paramilitary Rapid Support Forces (RSF).
The RSF has been at war with Sudan’s army since April 2023. The Sudanese military accused it of launching drone attacks “from inside Ethiopian territory,” which was the first public allegation of Ethiopian involvement in the conflict.
Yale School of Public Health’s Humanitarian Research Lab (HRL) revealed that analysis of satellite imagery and open-source data shows activity “consistent with military assistance to the RSF” at an Ethiopian base in Asosa, in the Benishangul-Gumuz region, between late December 2025 and late March 2026.
AFP, however, reported that the Ethiopian Government has refuted claims suggesting that it is supporting and hosting RSF camps.
Yale’s researchers said their findings “represent clear visual evidence over a five-month period” that the armed group’s attacks on Sudan’s southeastern Blue Nile State were being launched from within Ethiopia.
They added that the vehicles do not match those normally used by the Ethiopian military and have been observed supplying RSF units operating in Sudan’s Blue Nile state.
According to the report, some of the vehicles were later fitted with gun mounts “capable of holding heavy machine guns,” and objects consistent with 50-calibre weapons were also observed nearby.
Fighting intensified around Al-Kurmuk, a key army position, recently. An estimated 28,000 people were displaced by fighting in Blue Nile, including more than 10,000 from Al-Kurmuk alone.
Imagery previously analysed by AFP showed significant development at the airport, which previously served as a drone base.
A source in the army told AFP that the RSF brought thousands of fighters into Ethiopia in 2025.
