Nigeria's Boko Haram 'forces girls to blow themselves up'

Dr Fatima Akilu is the head of the Nigerian government's Countering Violent Extremism Programme.

She designed the de-radicalisation programme for suspected jihadists and has set up counter radicalisation initiatives and victim support programmes.

The BBC's Nigeria correspondent, Will Ross, asked Dr Akilu what had surprised her most about the captured members of Boko Haram she had met.
