Prior to 2014, Boko Haram used only male suicide bombers.
That means that Boko Haram has now used, by a significant margin, more female suicide bombers than any other terrorist group in history.
Some Boko Haram members may even offer their own children as bombers as a sign of allegiance to the cause. Children that grow up in the group are likely indoctrinated as well to glorify extreme violence, and some may aspire to be suicide bombers.
That only makes it likely the group, and its horrifying use of suicide bombers, will continue for the foreseeable future.
