NAIROBI — Sudan's paramilitary Rapid Support Forces, or RSF, and its allies signed a charter on Sunday to establish a unity government in the conflict-hit country.

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.

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.
