IDOMENI, Greece—As other children play among the tents of a rain-soaked refugee camp in northern Greece, 8-year-old Shaharzad Hassan sits quietly with her spiral notepad and a set of cheap marker pens.
The events in her life over the past 18 months have left her in little mood for fun. She prefers to draw. Sitting on the floor of a large tent crammed with 30 other families, she produces pictures of death in her hometown of Aleppo, Syria, and her harrowing journey to Europe.
