A witness and hospital records say a girl suicide bomber blew herself up, killing four others and seriously wounding 46 at a busy market in Potiskum in northeastern Nigeria, the ABC News reported.
Survivor Anazumi Saleh said the bomber appeared no more than 10 years old. He said she got out of a tricycle taxi in front of the market selling cell phones and accessories and detonated her explosives on Potiskum's main market day Sunday.
There was no immediate claim of responsibility but the attack bears all the signs of similar bombings by Boko Haram and raises fears that Nigeria's home-grown Islamic extremists are using kidnap victims as bombers.
The bombing comes amid reports that Nigeria's military is retaking towns and villages held by Boko Haram even as the extremists attack other northeastern communities.
