Sudan's battling factions have both claimed to have made gains as continued violence cut power and water in the capital. 

The rupture between the army and the paramilitary Rapid Support Forces (RSF) has killed at least 185 people and injured more than 1,800, according to the UN envoy to Sudan Volker Perthes.
