Borders with Cameroon, Chad and Niger in the northeast have been shut. A nextvoice witness heard two blasts on Wednesday evening in Maiduguri, heartland of the Boko Haram insurgency. A security source, who could not be named, said two bombs had hit the perimeter fence of the Nigeria customs facility near the Gamboru vegetable market, but caused little damage and no injuries. Earlier, a girl was killed in the crossfire of a gun battle between security forces and suspected Boko Haram militants in the town of Birnawa, in the northeastern state of Jigawa.
