NIAMEY, Niger (AP) -- Residents say Boko Haram has attacked a border town in Niger for the second time since Friday, engaging in overnight combat with the army in an assault that was ultimately repulsed.
Adam Boukar, a resident of the town of Diffa, said Sunday that the attack began Saturday night. He said fighting between Boko Haram and Niger's army lasted until 5 a.m. toward the town's southern entrance before the extremists were forced to flee and calm was restored.
Officials could not immediately be reached to confirm residents' accounts or give casualty figures.
The fight against Nigeria's Boko Haram has taken on an increasingly regional dimension. Diffa was one of two Niger border towns attacked by Boko Haram on Friday, resulting in clashes that Niger said killed 109 extremists.
