A self-defence group says Boko Haram insurgents have attacked a village in northeast Nigeria and beheaded the local chief and his son.
Abbas Gavi of the Vigilante Group of Nigeria said the Islamic extremists came to the village of Tallari before dawn on Monday.
He says they slit the throat of village chief Ba’ Lawan and his son, then set their home and others on fire.
Then they opened fire on fleeing villagers, killing two people and injuring others.
Tallari is near Chibok, the town from which the extremists kidnapped nearly 300 schoolgirls in April 2014. Dozens escaped on their own but 217 girls remain missing.
Boko Haram has said it will swap the girls for detained extremists but the government says negotiations have faltered as the group suffers a leadership struggle.
