(Save the Children) – A dusty police station in northern Iraq is a strange sort of paradise. But that is what it is to the eight families crammed in here on the hard, tiled floor. Babies are crying and young children are sleeping where they collapsed from exhaustion. They have walked over 60 miles, and scaled a mountain last night, to escape territory held by the Islamic State group. Many did it barefoot, including a five-year-old. But they survived. “I have come from jail to paradise,” one mother says to me, surrounded by her five children. “I am finally home.”
