West Africa fights back against Boko Haram

In 2015, West African countries fought against the jihadist militant group Boko Haram which controlled large areas of northeastern Nigeria.

The group, whose name means 'western education is forbidden', had killed thousands and displaced millions in the years preceding 2015.

They made worldwide headlines in 2014 when they kidnapped 276 girls from a boarding school.

Tim O’Callaghan speaks to retired Brigadier General Sani Kukasheka Usman, who was director of public relations for the Nigerian army in 2015.
