(HRW) – In May 2014, students at the Sabongari Primary School in  Gwoza, in northeastern Nigeria, stopped going to school. Hundreds, perhaps thousands, of members of the Islamist armed group Boko Haram had arrived in the middle of the night. They attacked the Gwoza government’s military base and then brought their weapons and ammunition into the school. A mother of two students told Human Rights Watch researchers, “Once we realized they were camped in the school, no one dared go near it again.”
