(Reuters) – United Nations peacekeepers in Central African Republic were hit on Wednesday with fresh accusations of sex abuses uncovered by a Thomson Reuters Foundation investigation amid growing concern about a failure to combat sexual misconduct. Three teenage girls displaced from their homes by fighting in the strife-torn country told the Thomson Reuters Foundation that they had sex with Congolese peacekeepers over several weeks, resulting in at least two pregnancies. The girls, aged between 14 and 17, live in temporary straw shelters in camps for internally displaced people (IDPs) close to where over 500 U.N. peacekeepers, mainly from Democratic Republic of Congo, Bangladesh and Cameroon are posted.
