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 Rapid Support Forces said it was paving the way to an end to the civil war. Critics called it an audacious gambit by a group that the United States has accused of genocide.

The paramilitary Rapid Support Forces (RSF), the Sudan People's Liberation Movement-North under the leadership of Abdelaziz El Hilu, 22 smaller rebel movements, and political and civil society groups signed the founding charter for a parallel Sudanese government in the Kenyan capital of Nairobi on Saturday evening.

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.

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.
