(UNICEF) – Last night, 13 educators and four of their children paid a most terrible price in the continuing conflict in Yemen – killed in an airstrike on a teachers’ office in Amran, just north of Sana’a. Twenty people, including one child, were injured. The latest casualties inflicted by all sides. The educators were gathered together to prepare exams for thousands of children who had missed the end of their school year because of this brutal conflict. Working after hours, they had brought their children with them, some of whom were playing outside when the bomb exploded. A selfless activity, turned in a moment into senseless bloodshed.
