"Abdul Fattah Burhan decided today to freeze the accounts of the rebel Rapid Support Forces and their companies in all Sudanese banks and their branches abroad," it said, citing concerns for budget money.
The announcement came shortly after media reported that the Sudanese military commander had fired the central bank governor, Hussain Yahia Jankol, and replaced him with a deputy, Borai El Siddiq. The reason for this change was not revealed.
On April 15, violent clashes broke out between the Sudanese regular armed forces and the Rapid Support Forces paramilitary group. The government forces accused the RSF of mutiny and launched airstrikes against their bases. Abdel Fattah Burhan, the head of the Sudanese military, issued a decree disbanding the RSF.
The parties have since introduced a number of temporary nationwide ceasefires but the conflict has not been settled yet.
So far, around 604 people have died and over 5,000 injured in the clashes in Sudan, according to the World Health Organization.
