The UN High Commissioner for Human Rights has warned of the possibility of revenge killings in the on-going conflict in South Sudan.
Navi Pillay was speaking during a trip to the towns of Bentiu and Bor where mass killings have taken place recently.
Her visit comes as negotiations, to end the four-month-long civil war, resumed in the Ethiopian capital Addis Ababa.
The BBC's Emmanuel Igunza travelled with Navi Pillay to Bor.
