The African Union's Peace and Security Council said on Sunday it strongly rejected any external interference that could complicate the situation in Sudan. Sudan's army appeared to gain the upper hand on Sunday in a bloody power struggle with rival paramilitary forces after blasting its bases with air strikes, witnesses said, and at least 59 civilians were killed including three UN workers. The fighting erupted on Saturday between army units loyal to General Abdel Fattah al-Burhan, head of Sudan's transitional governing Sovereign Council, and the paramilitary Rapid Support Forces (RSF), led by General Mohamed Hamdan Dagalo, known as Hemedti, who is deputy head of the council. It was the first such outbreak since both joined forces to oust president Omar Hassan al-Bashir in 2019 and was sparked by a disagreement over the integration of the RSF into the military as part of a transition towards civilian rule. Saudi Arabia, the United States, China, Russia, Egypt, the UN Security Council and European Union have appealed for a quick end to the hostilities that threaten to worsen instability in an already volatile wider region.
