Since August 25, Burmese security forces have been carrying out a campaign of ethnic cleansing against Rohingya Muslims in Rakhine State. Over half a million Rohingya have fled to neighboring Bangladesh to escape killings, arson, and other mass atrocities. The Rohingya, effectively denied citizenship under Burmese law, have faced decades of repression and discrimination. About 120,000 remain internally displaced from waves of violence in 2012 and 2016, in dire humanitarian conditions. Human Rights Watch researchers are reporting from the field on the crisis and its global impact.
