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,

Sudan’s paramilitary Rapid Support Forces and allies on Sunday 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.

Attacks by Sudan's Rapid Support Forces have killed more than 200 people over the past three days, activists said on Tuesday, as the paramilitary group delayed signing a political charter that could pave the way for a breakaway government.
