Gang rape, sexual mutilation, abductions and sexual slavery, as well as murder, has become a common thing in South Sudan. By soldiers and bandits.
According to a UN report for South Sudan February 2019, where UNICEF reports:
About targeted sexual violence, by children, including rape of girls as young as seven years. Elderly and pregnant women have also been raped.
The Commission also received reports of male victims of sexual violence.
Sexual and gender-based violence against men and boys is even more underreported than that against women and girls, as there is a higher level of stigma.
There are even reports of rape and murder of young and old.
