(Thomson Reuters Foundation) – The 21 Chibok schoolgirls freed by Boko Haram militants last month say they were not abused or raped during two-and-a-half years’ captivity in northeast Nigeria, a source close to the presidency said on Wednesday. Many girls kidnapped by the Islamist militant group have been used as sex slaves, fighters and even suicide bombers, according to rights groups including Amnesty International. But the 21 freed girls said the militants treated them well while they were held captive, according to a confidential report based on their two-week debriefing prepared for President Muhammadu Buhari and seen by the Thomson Reuters Foundation.
