Twelve-year-old Abdiwahab - not his real name - sobs as he recounts what happened to him as he escaped from the western Sudanese city of el-Fasher.
The young boy left el-Fasher on Sunday as it fell to the paramilitary Rapid Support Forces (RSF), the paramilitary group that has been fighting a two-and-a-half-year civil war against the army.
In a video received by the BBC, his face reflects deep sorrow and fatigue, his voice low as he describes being assaulted "many times" by RSF fighters.
Fearing reprisal attacks from RSF fighters, Abdiwahab had joined a wave of people - including some of his family - trying to get out.
The UN estimates that 60,000 have managed to get out of el-Fasher with many narrating horrendous stories of atrocities, including rape.
