A female suicide bomber blew herself up in a college in northern Nigeria’s biggest city of Kano on Wednesday, killing six people and critically wounding another six in the fourth such attack by a woman in Kano in less than a week, a security source said.
The bomber targeted youths who were looking at a notice board for national youth service in Kano Polytechnic, the source said.
