How should Boko Haram be dealt with? Al Jazeera English UP NEXT The Boko Haram armed group outraged much of the world in 2014 when it abducted schoolgirls in Chibok, a town in northeastern Nigeria. A few years after a military operation was launched against the armed group, it has claimed responsibility for a similar attack. Hundreds of schoolboys were kidnapped, this time in the northwest. The attack in Katsina state was initially blamed on bandit groups that have carried out kidnappings for ransom in the area. Hundreds of students are missing while others escaped. Boko Haram said it had targeted the school to fulfil a long-held aim of stopping Western education.
