'Crimes against humanity' in South Sudan
Both sides in South Sudan's conflict have committed crimes against humanity, including mass killings, sexual slavery and gang-rape, according to a UN report.
The "widespread and systematic" abuses were carried out in homes, hospitals, mosques, churches and UN compounds, it added.
The BBC's Alastair Leithead visited the oil town of Bentiu to investigate the atrocities.
