The Rohingyas are one of the most persecuted nations experienced state orchestrated torture and mass brutality. The internaitonally recognised fact finding mission on Myanrmar atrocities on Rohingyas labelled the persecution as a "textbook example of ethning cleansing" and international community knows it as a daylight massacre. They fled to nearby Bangladesh as they have no other choice left inside Myanmar. To understand Rohingya context in Bangladesh, I think practioners in humanitarian sector are in a great dilemma. History of the Rohingyas as a naiton and also the humanitarian response plans are important to get a clear picture of the context. And I hope that this book will help the humanitarian practitioners to find a smoother way towards their career and understanding.
