Syrian refugee boy Gays Cardak, 6, shows his drawing in a school library in the Yayladagi refugee camp in Hatay province near the Turkish-Syrian border, Turkey, December 16, 2015. "I'm going to be a doctor and an engineer. We the engineers will rebuild Syria, and I'll take the (soldiers) to hospital," Cardak said.
