I'm not sure, but take a look at this before and after photos of a kano female suicide bomber
Pic on the left is an alleged female suicide bomber but I can't verify that she's any of the ones that blew herself up during an attack in Kano last week....and the pic on the right is one of the missing Chibok girls. You know how some sources have fingered Chibok girls as the suicide bombers? though the Coordinator of the National Information Centre, Mr. Mike Omeri, has denied the girls involvement in the attacks....but it makes you wonder...the resemblance is strong but hopefully they are two totally different women.
