Sudan's cabinet will hold an extraordinary meeting on Monday amid an escalating political row between factions of the ruling Forces of Freedom and Change (FFC).
Pro-military Sudanese protesters rallied for a second day on Sunday, aggravating what civilian Prime Minister Abdalla Hamdok called the "worst and most dangerous crisis" of the country's precarious transition.
The protesters gathered outside the presidential palace in central Khartoum demanding the dissolution of Sudan's post-dictatorship interim government, saying it has failed them politically and economically.
The protests come as Sudanese politics reels from divisions among the factions steering the rocky transition from three decades of iron-fisted rule by Omar al-Bashir.
Pro-government supporters are planning a counter-protest on Thursday.
