A dozen independent United Nations experts, appointed by the UN Human Rights Council, expressed alarm Thursday about the escalation of violence in Sudan, particularly sexual violence committed in the conflict, primarily by the Rapid Support Forces (RSF). In a statement, they said gender-based violence (GBV), including sexual violence, is used as a tool of war and no longer concentrated in Khartoum or Darfur, but has spread to other parts of the country, such as Kordofan.
