Sitting on the floor of his makeshift school in the sprawling refugee camp of Cox's Bazar in Bangladesh, 11-year-old Omar spoke softly as he remembered his mother and father.
"My parents loved me so much. They looked after me very well," he said.
He explained how his parents were murdered by the Myanmar army in August 2017. Three of his brothers and two of his sisters were also killed.
"When I wake up every morning I start crying. Then I wipe my tears away and I get ready to go to school," he said.
