Of almost 60,000 registered women in South Sudan's camp for the Internally Displaced at Bentiu, more than half have been victims of sexual or physical violence.
Mary Chabak Jakoak, a social worker for the International Rescue Committee NGO, is trying to help them.
Internally-displaced herself, she lives in the camp and every week goes door to door, to inform on gender-based violence and help survivors find the right place to get help.
"When I was young I was forced to marry," she said.
"So what I saw here touched my heart. When I started working for the International Rescue Committee, I saw so many kinds of violence having consequences on people's lives that I felt I needed to do something. When I was young I didn’t know what to do so I didn’t want other women to suffer like me."
