Atrocities in Sudan's Darfur region are spreading town by town in an organized campaign that includes mass executions, rape, and ethnic targeting—amounting to war crimes and crimes against humanity, the International Criminal Court prosecutor told the United Nations (UN) Security Council. ICC Deputy Prosecutor Nazhat Shameem Khan said the situation in Darfur had "darkened even further," with civilians facing what she described as collective torture amid widening war between Sudan's rival military forces. The picture emerging is one of "organised, widespread, mass criminality," with atrocities used as a tool to assert control.
