French investigators now say the suspected mastermind behind last Friday’s Paris terrorist attacks that killed 129 people was in fact among those killed in a raid yesterday in a Paris suburb. ISIS has been front and center in the news coverage, but the Nigerian terrorist group Boko Haram has been killing people at a staggering rate for six years. It’s the group that kidnapped nearly 300 school girls last year. The Institute of Economics & Peace released a report yesterday called the Global Terrorism Index, which gave Boko Haram the distinction of being the world’s deadliest terrorist group. Yvonne Ndege, Al Jazeera’s West Africa correspondent, tells us more about the group. (AP/Muhammed Giginyu)
