Rebels in South Sudan are calling for an investigation into an alleged killing of civilians

Rebels in South Sudan are calling for an investigation into an alleged killing of civilians by government forces. It comes as the country's humanitarian crisis intensifies, as civil war and a famine continue to grip the nation. Fresh violence in South Sudan has forced hundreds more to join the more than a million people that have fled the country since fighting erupted in 2013. Their stories offer a glimpse into the brutality of the three-year civil war. Password Okot recently escaped to neighbouring Uganda after government forces allegedly killed 17 people on the border town of Pajok.
