Air strikes and artillery fire intensified sharply across Sudan's capital on Tuesday, residents said, as the army sought to defend its bases from paramilitary rivals it has been fighting for more than a month.
The air strikes, explosions and clashes could be heard in the south of Khartoum, and there was heavy shelling across the River Nile in parts of the adjoining cities of Bahri and Omdurman, witnesses said.
