Nigerian armed group, which has faced setbacks from growing regional offensive, pledges allegiance to ISIS. The leader of the Nigeria-based group Boko Haram has pledged allegiance to ISIS.

Boko Haram, which wants to establish an Islamic state in northern Nigeria, is believed to have control over about  20,000 square kilometres in the country’s northeast.

The armed group has focused its violence mainly inside Nigeria but has recently launched attacks in neighbouring Cameroon and Chad. So, what does the allegiance to ISIS mean for Nigeria?
