Nigeria attacks as Boko Haram releases video to disrupt Nigeria's elections

Twenty people have been killed in Nigeria following explosions at a military checkpoint outside the north-eastern town of Biu.

Troops at the checkpoint fired back, killing 17 of the insurgents believed to be members of Boko Haram.

Yesterday the group released a video in which its leader, Abubakar Shekau vowed to disrupt Nigeria's elections at all cost.

The 15-minute film was released via the group's newly created Twitter account, prompting some analysts to question whether they have been influenced by Islamic State.

Yesterday, a suicide bomber also killed four and injured five at a restaurant near a military checkpoint in Potiskum, north-east of the country.
