Shaken, scratched and left with just the clothes he is wearing, Ezzeldin Hassan Musa describes the brutality of Sudan's Rapid Support Forces (RSF) in the wake of the paramilitary group taking control of el-Fasher city in the Darfur region.

He says its fighters tortured and murdered men trying to flee.

Now in the town of Tawila, lying exhausted on a mat under a gazebo, Ezzeldin is one of several thousand people who have made it to relative safety after escaping what the UN has described as horrific violence.

On Wednesday, RSF leader Gen Mohamed Hamdan Dagalo admitted to violations in el-Fasher and said they would be investigated. A day later a senior UN official said the RSF had given notice that they had arrested some suspects.

About an 80km (50-mile) journey from el-Fasher, Tawila is one of several places where those lucky enough to escape the RSF fighters are fleeing to.

We left el-Fasher four days ago. The suffering we encountered on the way was unimaginable, Ezzeldin says.

We were divided into groups and beaten. The scenes were extremely brutal. We saw people murdered in front of us. We saw people being beaten. It was really terrible.

I myself was hit on the head, back, and legs. They beat me with sticks. They wanted to execute us completely. But when the opportunity arose, we ran, while others in front were detained.

Ezzeldin says he joined a group of escapees who took shelter in a building, moving by night and sometimes literally crawling along the ground in an effort to remain hidden.

Our belongings were stolen, he says. Phones, clothes - everything. Literally, even my shoes were stolen. Nothing was left.

We went without food for three days while walking in the streets. By God's mercy, we made it through.

Many arriving in Tawila are women and children, and reports indicate the men were particularly targeted by RSF fighters, suspected of being soldiers.

Ezzeldin is one of around 5,000 people thought to have arrived in Tawila since the fall of el-Fasher on Sunday.

A freelance journalist based in Tawila has conducted interviews with some of those who made the journey.

If someone resisted, they were beaten or robbed. They would take everything you had. People could even be executed. I saw dead bodies in the streets, recounts Yusra Ibrahim Mohamed, who fled after her husband, a soldier, was killed.

Health workers report that those who arrive are often severely malnourished, dehydrated, or suffering from injuries, placing significant strain on medical facilities.

As the situation unfolds, fears remain for those still trapped in areas controlled by RSF forces and the urgent need for humanitarian aid to reach them.

My message is that public roads should be secured for citizens, Ezzeldin pleads, or humanitarian aid sent to the streets. People are in a critical state - they can't move, speak, or seek help.
