The paramilitary Rapid Support Forces (RSF), in the eighth week of a power struggle with the army, attacked the Yarmouk complex on Tuesday, witnesses said.
Due to the proximity of fuel and gas depots, "any explosion could destroy residents and the whole area", he said.
Residents in Omdurman and Bahri reported towering flames were visible after nightfall at Yarmouk as clashes continued there.
The RSF quickly seized swathes of the capital after war erupted in Khartoum on April 15.
The army and RSF, which together staged a coup in 2021, fell out over the chain of command and military restructuring plans under the transition.
