UN reports gang-rapes, mass graves in Burundi

The United Nations has documented cases of Burundi's security forces gang-raping women during searches of opposition supporters' houses and heard witness testimony of mass graves, U.N. human rights chief Zeid Ra'ad Al Hussein said on Friday. Violence has worsened in Burundi since President Pierre Nkurunziza decided to run for a third term - a move opponents say was illegal - and won a disputed election in July.
