Geneva - The United Nations' top human rights official called on Nigeria's new President Muhammadu Buhari on Friday to investigate reports of horrifying crimes by Boko Haram rebels and alleged abuses by the military.
Zeid Ra'ad Al-Hussein said he had seen allegations of mass executions, rape and amputations of children by Boko Haram - a day after two blasts killed more than 30 people in the group's northeast heartland.
There were also reports Nigeria armed forces had mistreated people detained on suspicion of belonging to the group, he added.
“Civilians in northeast Nigeria have been living through horrifying acts of cruelty and violence by Boko Haram. These 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,” Zeid said in a statement.
Buhari, who was sworn in a week ago, said on Wednesday that Nigeria's army will take a bigger role in the effort to crush Boko Haram, by taking over from soldiers from Niger in occupying towns liberated from the Islamist militant group.
