Boko Haram's use of child bombers has increased over the last year, the UN's child agency says. 
According to BBC, UNICEF said that one in five suicide attacks now done by children, mostly girls, who are often drugged, were behind three-quarters of such attacks committed by the militant group in Cameroon, Nigeria and Chad. 
UNICEF says up to 1.3 million children have been forced from their homes across four countries: Cameroon, Chad, Nigeria and Niger. 
The UN report has been released as Nigeria approaches the second anniversary of the kidnapping by Boko Haram of more than 200 girls from their boarding school in the Nigerian town of Chibok. Their abduction sparked the global campaign Bring Back Our Girls, but none of the girls have yet been found.
