Myanmar's new threat of "clearance operations" is a disturbing echo of atrocities committed against the Rohingya minority and a reminder of the risks of ongoing impunity. Thousands of mostly ethnic Rakhine civilians have fled their homes. Less than three years ago, more than 700,000 ethnic Rohingya fled coordinated attacks that amounted to no less than genocide. The International Court of Justice has since ordered Myanmar to take emergency measures to prevent genocide, but this latest threat shows Myanmar has not changed. The failure of the United States and other countries to recognise previous attacks for what they are and to take further action is putting more lives at risk. We urge Secretary Pompeo to declare the attacks on the Rohingya as genocide and crimes against humanity and to take action to hold Myanmar accountable.
