Military build-up at Ethiopian base threatens Sudan’s Ed Damazin, Yale report says
August 28, 2026 (ED DAMAZIN) – A rapid accumulation of combat vehicles and military supplies at an Ethiopian military base near the border with Sudan poses a significant and imminent threat of an assault on the city of Ed Damazin by the paramilitary Rapid Support Forces (RSF), a conflict monitoring group said on Friday.
The Yale School of Public Health’s Humanitarian Research Lab (HRL) said satellite imagery showed a major escalation of activity and materiel at the Ethiopian National Defence Forces (ENDF) base in Asosa between Aug. 23 and Aug. 28.
Over that five-day period, researchers identified about 100 newly present light technical vehicles across three groupings, marking a sixfold increase compared with Aug. 23.
The imagery also revealed 15 vehicles consistent with armoured personnel carriers, 14 vehicle transport trailers, and at least eight cargo transport trucks. Several technicals showed visible weapon mountings, including at least five fitted with heavy weaponry.
Yale HRL assessed that the newly assembled fleet could field a force capable of transporting between 750 and 1,000 personnel, noting that each vehicle can carry six fighters.
The logistical build-up follows claims by Sudanese Armed Forces (SAF) sources that the RSF has been resupplied via Asosa airport during clashes across the border in Sudan’s Blue Nile state.
The observatory said logistics expansions had expanded steadily at the base, with at least 60 shipping containers arriving between late June and late August, followed by another 15 containers and the completion of a large vehicle storage shed measuring 70 meters by 17 meters.
The activity comes amid intensifying clashes in Blue Nile, where the RSF launched a counteroffensive in Kurmuk on Aug. 10. Satellite analysis previously identified fire damage in nearby Sali as well as destruction to the Kurmuk Hospital and the A40 bridge.
On Friday, the RSF said its fighters had seized two army installations in Blue Nile, including the headquarters of the SAF 13th Infantry Brigade in Bakori and another base in Surkum. Yale HRL said it could not independently verify those battlefield claims with available imagery.
The observatory warned that the military concentration sharply increases the risk of an assault on Ed Damazin, the capital of Blue Nile state, and could trigger civilian casualties and cross-border displacement into Ethiopia.
It added that the RSF’s push in Blue Nile appeared aimed at diluting the army’s troop strength in North Kordofan, thereby elevating the threat of simultaneous combat in and around the strategic city of El Obeid.
