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 Rapid Support Forces signed a charter with allied political and armed groups late on Saturday to establish a "government of peace and unity", signatories al-Hadi Idris and Ibrahim al-Mirghani told Reuters.

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.

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.

Sudan has condemned Kenya for hosting a meeting led by the rebels, and the UN is warning the move could further divide the war-torn country.

Sudan's paramilitary Rapid Support Forces and its allies have agreed to form a parallel government, they said Sunday, despite warnings such a move could further fragment the war-ravaged country.
