The Rapid Support Forces (RSF) Eid al-Adha cease-fire announcement came after Sudan's army confirmed on Monday that the RSF had taken the main base of a well-equipped police brigade in Khartoum and there were reports of fighting spreading for the first time to Blue Nile state near Ethiopia.
The RSF said it had captured dozens of armoured vehicles and pickup trucks after seizing the Central Reserve Police headquarters on Sunday, consolidating its position in southern Khartoum where several important military camps are situated.
Also on Monday, residents on social media reported an attack by the SPLM-N, Sudan's most powerful rebel group, in the city of Kurmuk in Blue Nile State, on the border with Ethiopia.
Reuters could not independently verify the reports. The United Nations mission in Sudan said hundreds of civilians had crossed the border into Ethiopia to seek safety due to clashes in Blue Nile on Sunday and Monday, while others appeared set to head north to Damazin, the state capital.
