Yola - Gunmen from Boko Haram shot dead at least 12 people during a four-hour siege on villages in northeast Nigeria overnight, two days after a deadly attack on a school, witnesses said on Wednesday.
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 at around 8:30 p.m. (1930 GMT), burning churches and houses and shooting sporadically at fleeing villagers, residents said.
The insurgents chased residents into neighbouring 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.
A local government chairman Maina Ularamu and army spokesman Captain Jafaru Nuhu confirmed the attacks but said it was too early to give a death toll.
The villages are in a hilly region running along the Cameroon border where soldiers have struggled to pin down insurgents who hide in rugged terrain and launch guerrilla attacks on areas they accuse of being pro-government.
Boko Haram gunmen killed 59 pupils at a boarding school in Yobe state, in the northeast close to Adamawa, in the early hours of Tuesday, in an attack President Goodluck Jonathan called "callous and senseless murder".
Jonathan's troops are struggling to stem Boko Haram's insurgency, although they have restricted attacks mainly to the country's remote northeast corner in recent months, far away from commerical capitals and southern oil fields.
Militants from Boko Haram, whose name means "Western education is sinful" in the northern Hausa language, have frequently attacked schools in the past. A similar attack in June in the nearby village of Mamudo left 22 students dead.
They have killed more than 300 people this month, mostly civilians, including in two attacks last week that killed around 100 each, one in which militants razed a whole village and shot panicked residents as they tried to flee.
