(Reuters) - Niger's forces killed 109 fighters from the Islamist militant group Boko Haram on Friday as they repulsed attacks on the southeastern town of Bosso, near the Nigerian border, Niger state television said.

Four soldiers from Niger were killed in the fighting against Boko Haram, whose insurgency is spreading from Nigeria to neighboring states.
