RSF, allies seize parts of Geisan in Sudan's Blue Nile state

August 11, 2026 (GEISAN) – Rapid Support Forces (RSF) took control of large parts of Geisan town in Sudan's Blue Nile region on Tuesday, though the Sudanese army retained control of its primary military base amid heavy ongoing clashes, sources said. Supported by fighters from the SPLM-N, the RSF launched a violent early morning assault on Geisan using heavy artillery and drones. Battles were concentrated around the 13th Infantry Brigade headquarters, which remains under military control. Pro-RSF platforms published video clips showing their fighters inside the town, including the main market. Local sources reported that the market was subjected to widespread looting and vandalism during the advance. The Sudanese army intensified drone strikes targeting RSF concentrations in the town, forcing paramilitary forces to withdraw from several newly captured positions. The local government in Geisan confirmed the joint RSF and SPLM-N attack, stating that the army and allied forces were fighting across multiple fronts. Conversely, "Tasis" forces allied with the RSF claimed full control of Geisan and alleged heavy casualties were inflicted on the army. Platforms close to the Blue Nile regional government accused the RSF of deploying foreign mercenaries from Ethiopia and South Sudan in the offensive. Geisan is strategically important because of its proximity to the Ethiopian border. The International Organization for Migration reported that the renewed fighting has displaced approximately 2,500 people.
