Boko Haram seizes control of the Nigerian town of Chibok
Boko Haram militants have seized the north-eastern Nigerian town of Chibok, from where they kidnapped more than 200 schoolgirls in April.
Militants attacked and took control of the town, in Borno state, on Thursday evening, residents who escaped told the BBC.
Boko Haram has repeatedly targeted villages around Chibok over recent months.
The group says it is fighting to create an Islamic state in Nigeria.
The schoolgirl kidnappings in Chibok caused worldwide outrage and sparked a social media campaign.
Separately on Friday, a suicide attack at a petrol station in the northern city of Kano left at least six people dead, police said.
