Construction of an extensive earthen wall, referred to as “berms,” is underway around the besieged Sudanese city of el-Fasher, as reported by the Yale University Humanitarian Research Lab. Through satellite imagery, researchers have documented over 31 kilometers (19 miles) of these barriers built since May in regions surrounding the city currently controlled by the paramilitary Rapid Support Forces (RSF).
El-Fasher, the last significant stronghold of the Sudanese army in Darfur, has been under siege for more than a year amidst ongoing conflict with the RSF, which escalated in April 2023. The Sudan Doctors Network has reported an increase in RSF offensives, including deliberate attacks on civilian populations. Recent shelling reportedly resulted in nearly 24 civilian deaths and over 55 injuries in the city center, with specific targeting of hospitals leading to significant casualties among patients and medical staff.
While both the RSF and the Sudanese army have utilized berms defensively, Yale’s analysis indicates that the RSF may be intentionally creating a “kill box” around the city. The report maps the construction of these earthen walls, indicating significant segments completed between May and August 2025.
The physical barrier complicates movement in and out of el-Fasher, where approximately 300,000 people reside. Reports suggest that civilians attempting to flee face danger and potential targeting by RSF forces. Humanitarian organizations have been largely unable to assist the city for months, exacerbating issues such as food shortages, medical access, and ongoing bombardment. Civilians describe their situation as increasingly dire, with some citing a lack of resources to escape and an overwhelming sense of danger if they do choose to leave.
Former Darfur governor Adeeb Abdel Rahman Youssef has called upon the UN Security Council to intervene and protect the civilians of el-Fasher, emphasizing the dire circumstances faced by the local population. Current research indicates that the construction of the walls is still continuing.
