Bentiu, South Sudan – Nyagai desperately wants her two girls to come home from a camp where relentless rape, starvation, and sickness pervades.

Her third daughter, 17, was released by fighters after a month when she lost control of her bowels from being raped so much, and her captors “saw she was going to die”.

“She said that many, many, many men raped her and when she came back she had to go to hospital,” said Nyagai, whose name has been changed to protect her from reprisals, along with other victims quoted in this story.
