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.
Those in Tawila told the BBC that men making the journey were particularly likely to be subjected to scrutiny by the RSF, with fighters targeting anyone suspected of being a soldier.
Ezzeldin is one of around 5,000 people thought to have arrived in Tawila since the fall of el-Fasher on Sunday.
Many have made the entire journey on foot, travelling for three or four days to flee the violence.
A freelance journalist based in Tawila, working for the BBC, has conducted among the first interviews with some of those who made the journey.
In the next tent in the clinic run by medical charity Médecins Sans Frontières (MSF), Yusra Ibrahim Mohamed describes making the decision to flee the city after her husband, a soldier with the Sudanese army, was killed.
My husband was in the artillery, she says. He was returning home and was killed during the attacks.
Alfadil Dukhan works in the MSF clinic. He and his colleagues have been providing emergency care to those who arrive - among them, he says, are 500 in need of urgent medical treatment.
Those arriving this week in Tawila join hundreds of thousands there who fled previous rounds of violence in el-Fasher. Before its seizure by the RSF on Sunday, the city had been besieged for 18 months. Hundreds of thousands were displaced in April when the RSF seized control of the Zamzam camp close to the city, at the time one of the main sites housing people forced to flee fighting elsewhere.
With the continued conflict, many fear for those left behind in the dangerous journey from el-Fasher to Tawila. Ezzeldin pleads for stronger humanitarian support to ensure that assistance reaches those who remain trapped.
