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 charter states creating a government of ‘peace and unity’ despite concerns from rights groups and global actors.

The war in Sudan has killed more than 24,000 people and driven over 14 million people — about 30% of the population — from their homes, according to the United Nations. An estimated 3.2 million Sudanese have escaped to neighboring countries.

Over 20 political parties, 10 civil organizations, and 5 military groups led by RSF were among the signatories.

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.

Sudan's paramilitary Rapid Support Forces and its allies have agreed to set up a parallel government, sources said Sunday, despite warnings such a move could further fragment the war-ravaged country.A spokesman for UN chief Antonio Guterres warned the move could "increase the fragmentation of the country and risk making this crisis even worse".
