A special investigation into the mass exodus of Rohingya Muslims from Myanmar. We examine evidence that Myanmar's security forces used systematic rape and terror tactics to expel hundreds of thousands of Rohingya from the country.
Since security forces began a violent campaign in August 2017, up to 700,000 people have fled their homes to travel across the Myanmar border to nearby Bangladesh.
Thousands of civilians, including children, are thought to have been killed, in a story of systematic discrimination, state-sanctioned violence and, ultimately, mass murder.
In this special hour-long Dateline film, reporter Evan Williams hears first-hand about brutal killings and attacks on Myanmar's persecuted Rohingya Muslim population - and looks at whether Myanmar's leaders, including Nobel Peace Prize laureate Aung San Suu Kyi, should be held accountable for these atrocities.
"She had gone from a human rights heroine, a beacon of democracy, to a politician catering to the military, wanting the military to support her," says former US Ambassador to the United Nations, Bill Richardson.
Aung San Suu Kyi rejects the criticism and says that the military is simply hunting terrorists, but a network of Rohingya activists were secretly filming what was really happening, risking their lives in the process.
Their ground breaking accounts of video evidence of several unknown massacres, provides Dateline with the first proper look at whether the killing of civilians could be genocide.
