a female bomber arrested in Kano in 2014

Women and girls, who have escaped Boko Haram have reported undergoing a systematic training programme to train them as bombers, UNICEF has reported.

It said that 85 per cent of the suicide attacks by women globally in 2014 were in Nigeria.

In May 2015, it was reported that children had been used to perpetrate three-quarters of all suicide attacks in Nigeria since 2014.

Many of the bombers had been brainwashed or coerced.

As the Nigerian military recaptures territory from Boko Haram, abducted women and girls are being recovered.
