Islamic State has accepted a pledge of allegiance from Nigeria's militant group Boko Haram.

In the tape, which has not been verified, an IS spokesman says the aim of establishing a caliphate has now been expanded to West Africa.

Last week, Boko Haram posted a message saying it wanted to join ranks with IS.

Boko Haram began a military campaign to impose Islamist rule in northern Nigeria in 2009.
