Four killed by girl suicide bomber
A girl suicide bomber blew herself up in a busy market in north-eastern Nigeria, killing four other people and seriously injury 46, witnesses said.
Survivor Anazumi Saleh said the bomber appeared to be no more than 10 years old.
He said she got out of a tricycle taxi in front of the market selling mobile phones and accessories and detonated her explosives on Potiskum's main market day.
There was no immediate claim of responsibility but yesterday's 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 north-eastern communities.
Meanwhile, a new group releasing propaganda for Boko Haram denied a Ministry of Defence statement that troops seized back the border garrison town of Baga on Friday.
"Baga still is under the control of the mujahideen and any claim by the regime that they took the city is their usual lie," said a brief message posted on the Twitter account of Al-Urwa Al-Wuthqa, according to the Site intelligence monitoring service.
The Associated Press was trying to verify the situation in Baga, a town on Lake Chad and the border with Cameroon where the extremists are accused of killing hundreds of people in a January attack after Nigerian troops fled.
The government hopes the military will be able to reclaim enough territory to allow presidential elections on March 28, which Boko Haram is threatening to disrupt.
The vote looks likely to be the most closely contested in the history of Nigeria, Africa's most populous nation and its biggest oil producer.
Boko Haram has warned it will disrupt the elections by attacking polling stations and denounced democracy as a corrupt Western concept.
