Protesters have massed outside the army complex in central Khartoum since April 6, initially to demand the overthrow of leader Omar al-Bashir, AFP reported.
But since his ouster by the army on April 11, the protesters have kept up their sit-in, demanding that the military council that took over hand power to a civilian administration.
Despite international support for the protesters, the 10-member council has so far resisted, although three of its members resigned on Wednesday under pressure from the street.
The resignations triggered jubilation among the protesters, who massed in their tens of thousands on Thursday in response to a call from their leaders for a "million-strong" march.
Despite the scorching heat, the protesters were back in numbers on Friday, an AFP correspondent reported.
The military council, led by General Abdel Fattah al-Burhan, has said it has assumed power for a two-year transitional period.
Protest leaders have held several rounds of talks with the council and the two sides have agreed to set up a joint committee to chart the way forward but there has so far been no breakthrough.
Washington has thrown its weight behind the protesters.
At a summit hosted by Egyptian President Abdel Fattah al-Sisi on Tuesday, African leaders conceded that more time was needed for a transition to civilian rule.
Their statement angered the protesters who held a rally outside the Egyptian Embassy on Thursday.
The African Union had taken a strong line setting an end of April deadline for the military council to hand power to civilians or face suspension from the 55-nation bloc.
