Thousands of civilians have been killed and more than a million displaced since the conflict in South Sudan began in December 2013. Both government and opposition forces have targeted civilians, committed acts of sexual violence, looted, damaged or destroyed medical and humanitarian facilities and obstructed the delivery of desperately needed humanitarian aid. The conflict has pitted ethnic groups against each other and many civilians have been targeted in ethnically motivated attacks. This report shows the extent to which all parties to the conflict have disregarded international human rights and humanitarian law.
