Employees of Sudan state television said that the decision was made to stop the propaganda broadcasting by a paramilitary force engaged in a conflict with the army to control the capital.
The army denied the paramilitary Rapid Support Forces' claims that it had taken control of state TV and other vital sites as violence broke out around Khartoum on Saturday.
By Sunday, it appeared the army was winning the battle in Khartoum.
The RSF entered the central state broadcaster headquarters in Omdurman, across the Nile from Khartoum, and used radio networks to broadcast content supporting the RSF, according to state media personnel who spoke anonymously.
