Over 55,000 people have been forced to flee the city of Singa in southeastern Sudan, where clashes between the paramilitary RSF and the Sudanese military are raging, according to the UN's humanitarian agency Ocha.
The reports come after RSF claimed on Sunday that the group had taken over the military's most important facility in the city.
Ocha writes on the social platform X that the residents are now fleeing to other states, several of which are already home to thousands of refugees.
Since the fighting broke out in Sudan in April 2023, when the previously cooperating parties in the army and the paramilitary group RSF began fighting each other, tens of thousands of people have been killed and tens of thousands more have been forced to flee.
The war has led to one of the world's worst ongoing humanitarian crises.
