Reuters has published an extensive report into the killing of 10 Rohingya men in Myanmar in September, pulling from photographs and eyewitness accounts to describe how villagers and paramilitary forces killed the men execution-style and buried them in one grave.The investigation made headlines long before it was published.While working on the story, two Reuters journalists were arrested by Myanmarese authorities and accused of violating the Official Secrets Act. The men, Wa Lone and Kyaw Soe Oo, have been detained since December and face up to 14 years in prison.The journalists' detention has prompted outcry from governments and human rights groups around the world. Reuters says the two men are innocent of wrongdoing and were arrested for doing their jobs, as "journalists who perform a crucial role in shedding light on issues of global interest."Now the world can see the results of their work in "Massacre in Myanmar," the story published by Reuters overnight.Wa Lone, Kyaw Soe Oo, Simon Lewis and Antoni Slodkowski describe how in early September, paramilitary troops and Buddhist villagers tied 10 men together and killed them with machetes and gunfire.For months, the persecuted Rohingya Muslim minority group in Myanmar has been targeted in a wave of violence that the United States has denounced as "ethnic cleansing." In a single month, more than 6,700 Rohingya Muslims were killed in Rakhine state, where the conflict erupted, according to Doctors Without Borders.Hundreds of thousands of refugees have fled the violence, setting up in makeshift shelters in camps in Bangladesh. The conditions in those camps are dire, as NPR's Jason Beaubien has been reporting.Those refugees have shared credible stories of horrifying massacres, systematic rapes by soldiers, and the burnings of entire villages.And last week, The Associated Press published a report on the use of mass graves to conceal systematic executions of Rohingya prisoners, pulling from photographs and testimony from refugees.The new Reuters story, in its graphic, disturbing content, is in line with the previous accounts of atrocities in Rakhine state.But the sourcing of the Reuters report is unusual, as the news organization notes:
