Forces fighting alongside Sudan's army said on Friday they had intercepted a substantial quantity of military supplies from a convoy destined for the rival Rapid Support Forces (RSF) in North Darfur.

Sudan's Rapid Support Forces (RSF) is establishing a parallel government to gain diplomatic legitimacy and access to advanced weaponry, challenging its army-led rival. The RSF aims for international recognition and increased military support after losing ground in the protracted conflict.

Activists said three days of attacks by the paramilitary group had killed more than 200 people in White Nile state, which has emerged as a key battleground as the army regains territory.

A parallel government being set up by Sudan's Rapid Support Forces (RSF) aims to grab diplomatic legitimacy from its army-led rival and ease access to advanced weaponry, politicians who back it and paramilitary sources told Reuters.

Sudan’s paramilitary Rapid Support Forces and allies have signed a charter that paved the way for the establishment of a parallel government, as Sudan’s army made advances recently against the rival groups.

Sudan's army and allied groups could face formidable battlefield challenges if the recent political agreement between the paramilitary Rapid Support Forces (RSF) and a powerful faction of a southern rebel group becomes a military alliance,

The RSF has seized most of the western Darfur region and swathes of the Kordofan region in an almost-two-year war, but is being pushed back from central Sudan by the Sudanese army.
