Boko Haram, whose fight for an Islamic state in northern Nigeria has killed thousands and made them the biggest threat to security in Africa's top oil producer, is increasingly preying on the civilian population.
Gunmen riding in 13 pick-up trucks sped into Kirchinga village in Adamawa state in the evening, burning churches and houses and shooting sporadically at fleeing villagers, residents said.
The insurgents chased residents into neighboring Shuwa village, where they torched the house of a local bishop, a theological school and a police station.
The owner of a bakery, Martha Yakubu, said she counted 12 dead bodies, including two of her workers. Banks, small schools and dozens of houses were attacked.
