(MSF) – Since 25 August 2017, nearly 700,000 Rohingya refugees have arrived in Bangladesh. They join tens of thousands of others who were fled there after previous periods of tension and violence in neighbouring Rakhine state, Myanmar. The thing I find most striking about this situation is its magnitude – the sheer number of people who have crossed the border in a short space of time, barely six months. In fact, people continue to arrive today.
