Sudan's paramilitary Rapid Support Forces (RSF) said it had seized the main base of a heavily armed police unit on Sunday as it sought an edge in its war with the army during heavy fighting in the capital Khartoum.

The RSF in a statement said it had taken full control of the large base belonging to the Central Reserve Police southern Khartoum and posted footage of its fighters celebrating inside the facility, some removing boxes of ammunition from a warehouse. 

It later said it had captured 160 pick-up trucks, 75 armoured personnel carriers, and 27 tanks. Middle East Eye was not immediately able to verify the footage or the RSF statements. There was no immediate comment from the army or the police. 

Since late Saturday, fighting has surged in the three cities that make up the wider capital - Khartoum, Bahri and Omdurman - as the conflict between the army and the RSF entered its 11th week. 

Witnesses also reported a sharp increase in violence in recent days in Nyala, the largest city in the western Darfur region. The UN raised the alarm on Saturday over ethnic targeting and the killing of people from the Masalit community in El Geneina in West Darfur.
