Protests have rocked Sudan for nearly four months, resulting in the ouster of president Omar al-Bashir last week after three decades of iron-fisted rule.
But in less than a week, the initial jubilation has turned into anger against Sudan's new military rulers as protesters remain camped outside the army complex.
At first they pressed the army to back their calls to oust Bashir.
Since his departure, they have called on the ruling military council to meet the demands of their "revolution".
On Monday, they hardened their position, demanding the military rulers simply exit.
Below are key demands which the Sudanese Professionals Association (SPA) and the umbrella group Alliance for Freedom and Change say must be met for the sit-in to end:
* Dissolving the transitional military council immediately and replacing it with a civilian one with the army also represented.
* An immediate transfer of power to a transitional civilian government to govern for a four-year term, followed by elections.
* The dissolution of Bashir's National Congress Party, with its top leaders brought to justice -- including the ousted president.
* The confiscation of NCP properties.
* The re-instatement of the country's 2005 constitution, which the military council suspended shortly after ousting Bashir on April 11.
* The release of all civilians arrested in connection with the protest movement, as well as soldiers and police detained for refusing to shoot at protesters.
* An end to the state of emergency Bashir imposed on February 22.
Several of the demands have been presented by The Alliance for Freedom and Change to the military council.
The SPA, a grouping of teachers, engineers and doctors that initially spearheaded the campaign, has urged protesters to keep up the sit-in.
The chief of the military council, General Abdel Fattah al-Burhan, has vowed to "uproot" Bashir's regime.
The council says the ousted president is in custody, but has not specified his whereabouts or of other senior regime leaders.
However, it has said it will not extradite Bashir, who is wanted by the International Criminal Court on charges of genocide and crimes against humanity.
Bashir has denied the charges.
