The United Nations has asked President Muhammadu Buhari to investigate and prosecute “horrifying” allegations of executions, rape and amputations of children by the Boko Haram sect.

The UN High Commissioner for Human Rights, Mr. Zeid Ra’ad Al-Hussein, says that reports of violations committed by Nigerian armed forces should be investigated also and perpetrators brought to justice.

According to the UN official, civilians in North-east Nigeria have been living through horrifying acts of cruelty and violence by Boko Haram.

These, he says include wanton killings, summary executions, forced participation in military operations – including the use of children to detonate bombs, forced labour, forced marriage and sexual violence, including rape.
