Nadia Murad, a Yazidi woman tortured and raped by Islamic State militants, and Denis Mukwege, a Congolese gynecologist, were jointly awarded the 2018 Nobel Peace Prize on Friday. The winners were chosen for their "efforts to end the use of sexual violence as a weapon of war." Mukwege is an expert in the treatment of serious sexual injuries and, together with his colleagues, has treated some 30,000 rape victims in the Democratic Republic of the Congo. Murad became the face of a campaign to free the Yazidi people and stop human trafficking after escaping the Islamic State in 2014.
