Djafaruddin says he has recovered from the trauma of collecting bodies when the world's deadliest tsunami devastated Indonesia's western coast two decades ago, but he still breaks down when thinking about the orphaned children.

"When I saw the condition in the river with bodies strewn about... I screamed and cried," he said.
