This week, the head of the United Nations Children’s Fund, UNICEF, told global leaders Sudan’s humanitarian crisis is the world’s biggest and most devastating. A new UNICEF report says 30 million people are in need of humanitarian aid, more than half of them children. Many of them face threats of violence and sexual assault on a daily basis.
