From Myanmar they flee, more than half of the country’s 1.1 million Rohingya escaping to Bangladesh since August. Renewed, sustained, and seemingly relentless attacks by Myanmar’s military and alleged Buddhist civilian mobs prompted a top U.N. official to label the situation a “textbook example of ethnic cleansing.”

In their quest for safety, Rohingya have, en masse, made treacherous journeys on which many have collapsed, starved to death or drowned, only to get trampled by elephants and endure further hard conditions once crossing the border.

For eight days in early October, Magnum’s Moises Saman travelled to the Bangladeshi border with Myanmar, where tens of thousands were fleeing ethnic violence in Myanmar’s northern Rakhine State.

The camps that have been there for several years are struggling with the sudden, massive, influx of population as locals hurriedly attempt to build extensions. Cramped and damp conditions have led NGOs to warn of a possible cholera outbreak.
