A security source has told BBC Africa that Boko Haram has hoisted its flag in three villages in the north-eastern part of the country after over-running them.
Nigeria's militant Islamist group Boko Haram has hoisted its flag in three villages in the north-east after over-running them yesterday, a security source has said.
The militants slaughtered at least eight people, including a village elder, during the attack, the security source and residents said.
The villages - Kubirivour, Boftari and Kuburmbalah - are near Chibok town, from where the militants captured more than 200 schoolgirls in 2014.
Others sources said the militants were still in control of Malam Fatori town, on the Nigeria-Niger border.
Last Sunday, Nigerian troops recaptured the town from the jihadists. However, the militants reinforced their ranks and regained control of the town.
