The head of Sudan's ruling military council General Awad Mohamed Ahmed Ibn Auf has announced his resignation in a statement broadcast on state television on late Friday.
He also named the Army Chief of Staff Abdel Fattah Abdelrahman as the new head of a transitional military council.
Protesters in Khartoum were celebrating Ibn Aufo's uster in the streets.
On Thursday, Ahmed Ibn Auf announced the establishment of a military council that would govern the country for two years.
Earlier on Friday, Sudan’s ruling military council promised the country would have a new civilian government, and that the transition period announced on Thursday to last two years at most or much less if chaos can be avoided.
But Sudan’s main protest organizing group on Friday rejected the transitional military council promise to set up a civilian government and hand over power to an elected president within two years.
“Our demands are clear, just and legitimate, but the coupists (the regime’s security committee)... are not capable of creating change, and they do not have the safety and stability to stay in power,” the Sudanese Professionals Association said in a statement.
“This is not to mention the peaceful demands of handing over power to a transitional civilian government as one of the conditions that needs to be implemented.”
