(NRC) – Fifteen-year-old Mahmoud Nafa sits in a tent in the Kilo 18 displacement camp in Anbar in western Iraq, with his six-month-old cousin in his lap. Surrounded by his family, it’s easy to see that they are close. The baby gurgles happily as Mahmoud smiles at him, masking the sorrow that hangs heavily in the air. His smile is wide, but it’s hard not to notice that the skin around his left eye is lighter than the rest of his face. A stress condition, his grandfather says.
