Kano - Boko Haram has burnt down a village neighbouring the northeast Nigerian town of Chibok where the group kidnapped over 200 schoolgirls two years ago, local residents said on Wednesday.

"They attacked the village around 8:00 pm, firing heavy guns which made people flee into the bush," Samson Bulus from nearby Kautikeri village told AFP. "The Boko Haram raiders looted homes and shops, taking along food supplies and livestock before burning the entire village," he said. Luka Damina, another Kautikeri resident said troops in Chibok engaged the attackers in gun battle but were subdued by the insurgents.Follow News24 Africa on Facebook and Twitter. "The Boko Haram fighters overpowered the soldiers and seized a van with a machine gun mounted on the deck from the soldiers," he said.
