Geneva: 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, UN human rights chief Zeid Ra`ad Al Hussein said on Friday.


“The 11 December attacks against three military camps and the large-scale human rights violations that occurred in their immediate aftermath appear to have triggered new and extremely disturbing patterns of violations,” Zeid said in a statement.
