Sudan's transitional military council has arrested members of the former government and promised not to disperse protesters, according to BBC.
A spokesman also urged the opposition to pick the next prime minister and vowed to implement their choice.
Months of protests in Sudan led to the ouster and arrest of long-time leader Omar al-Bashir on Thursday.
Demonstrators have vowed to stay on the streets until there is an immediate move to civilian rule.
A sit-in is continuing outside the defence ministry in the capital Khartoum.
