It is exactly 10 years since the leader of Nigeria’s militant Islamist group Boko Haram, Mohammed Yusuf, was killed in police custody.

His death sparked a campaign of terror in Nigeria that has left more than 30,000 people dead and displaced more than two million people.

The BBC’s Nigeria correspondent Mayeni Jones examines the roots of the militant group, its rise to global infamy and whether it will remain a force in the region in the next decade.
