The U.N. court trying suspects of the 1994 Rwanda genocide has found a female former government minister and her son guilty of war crimes and gave both life sentences, marking the first time a woman has been convicted of genocide.

Pauline Nyiramasuhuko, Rwanda’s former minister for family and women affairs, and her son, Arsene Ntahobali, a former militia leader, on Friday were both found guilty of genocide, war crimes and crimes against humanity, including rape.
