In a statement released in the early hours of Thursday, the military accused the Rapid Support Forces (RSF) of clearly breaking the law.

There are growing fears of a confrontation between the two sides.

The RSF leader, Mohamed Hamdan "Hemeti" Dagolo, played a key role when the army seized power in Sudan in 2021.

This week leaders failed to meet a deadline to form a civilian-led government.

The breakdown of the talks has been blamed on differences between rival military factions.
