This Refugees International (RI) report warns that a humanitarian catastrophe is imminently threatening nearly one million Rohingya refugees in Bangladesh. Survivors of the brutal campaign of ethnic cleansing in Myanmar, the Rohingya refugees in Bangladesh now face the onset of the monsoon and cyclone seasons. The humanitarian response, including preparation for the monsoon season, has been significant and substantial – but it has also been hamstrung by obstacles and lack of effective management and coordination by the Government of Bangladesh and the United Nations system. Failure to overcome these challenges is unnecessarily putting lives at risk.
