Militants have stormed a remote village in north-eastern Nigeria, killing at least 33 people and kidnapping dozens, a survivor has told the BBC. He said that suspected Boko Haram militants had seized young men, women and children from Bintiri village. The attack happened on Sunday but news has only just emerged, after survivors reached the city of Maiduguri. Meanwhile, Cameroon's army says it has killed 116 Nigerian militants who had attacked one of its bases. No group has said it carried out either attack but officials have blamed Boko Haram. More than 2,000 people have been killed this year alone, mostly in north-eastern Nigeria, near the border with Cameroon. The survivor said that after the attack, he returned to the village of Bintiri and helped bury 33 bodies. His testimony was confirmed by a local official, neither of whom wanted their names to be published.
