Islam fills the education vacuum for refugee Rohingya children

Fleeing persecution in Myanmar, a million Rohingya refugees have fled to neighbouring Bangladesh. They now live in the Kutupalong camp, the world's biggest refugee camp. The majority of them are under 18, a generation that will grow up with almost no education. Instead, Hefazat-e-Islam, an Islamist organisation, is spreading its influence in the Kutupalong camp and already claims to have 350,000 students. Our correspondents report.
