(Thomson Reuters Foundation) – When a colleague asked Margee Ensign to help her sister who had been snatched by Boko Haram from her school dormitory in Chibok and escaped, the president of the American University of Nigeria could not refuse. Ensign decided to offer scholarships to girls who managed to flee the Islamist militant group after it abducted more than 270 of their classmates in April 2014, its most high-profile assault in a seven-year insurgency to create an Islamic caliphate. Of the 57 girls who escaped after the night-time raid in northeastern Nigeria, 24 accepted the university’s offer.
