The Islamist militant group, which kidnapped hundreds of teenage girls from a school in northeast Nigeria, has abducted eight more girls.
Suspected Boko Haram Islamist militants kidnapped the girls, aged between 12 and 15, on Sunday night in the village of Warabe, in Borno state.
On Monday, Boko Haram's leader threatened to 'sell' more than 230 girls the group had kidnapped from their school on 14 April.
According to the BBC, the insurgency by Boko Haram has left thousands dead since 2009.
Boko Haram leader Abubakar Shekau released a video on Monday confirming that his group had abducted them, the report added.
