Nigeria kidnaps: Prisoner swap 'not on the table'

Nigerian Interior Minister Abba Moro has said that swapping prisoners in exchange for girls kidnapped by the Islamist militant group Boko Haram is an option that is "not on the table".

The group released a video on Monday apparently showing about 130 girls kidnapped from a school in northern Nigeria on 14 April.

In the film Boko Haram leader Abubakar Shekau said the children would be held until imprisoned militants were freed.

Boko Haram has abducted more than 200 girls in recent weeks and previously threatened to sell them.
