The Sudanese army’s advance into West Kordofan could disrupt RSF militia supply routes between Kordofan and Darfur.

Since the early months of the war that erupted in April 2023, the Sudanese-Chadian border has been central to the mutual accusations regarding the sources of arms for the Rapid Support Forces (RSF).

As fighting intensifies across Darfur and reports of mass killings, sexual violence, and ethnically motivated detentions continue to mount, covert field teams are quietly gathering evidence from areas that remain largely inaccessible to journalists and human rights organizations.

In a covert operation, a force of around 280 fighters, including field commanders, arrived in Khartoum on July 23, 2026, after breaking away from areas controlled by the RSF militia and declaring their allegiance to the Sudanese army.

The Joint Force of armed struggle movements announced on July 12, 2026, that it had regained control of the Bir Saliba area, following clashes with the UAE-backed Rapid Support Forces.
