Over the past 14 years Boko Haram has wreaked havoc in Nigeria and neighbouring countries.

The group gained international notoriety with the kidnapping of more than 200 schoolgirls in Nigeria in 2014 which sparked the ‘Bring Back Our Girls campaign’.

Their attacks also spread to Cameroon, Chad and Niger leaving thousands dead and three million people displaced according to the United Nations. Le Spectre de Boko Haram, an award winning documentary, recently screened in at the London Film Festival.

It tells the story of three children living in a village in northern Cameroon, a region regularly attacked by Boko Haram in cross border raids. The film’s director Cyrielle Raingou spoke to Africa Daily’s Sharon Hemans about why she decided to tell this story and the challenges she faced as a woman film director.
