Kahlan, a 12-year-old former child soldier, demonstrates how to use a weapon, at a camp for displaced persons where he took shelter with his family, in Marib, Yemen in this July 27, 2018 photo. Houthi rebels took Kahlan and his classmates, promising to give them new school bags, but instead they were enlisted and trained as fighters tasked with carrying supplies to the front lines. There, he had to elude explosions and airstrikes that left mangled casualties on the battlefield. “The sight of the bodies was scary,” he said. (AP Photo/Nariman El-Mofty)
