BANGKOK — The news agency Reuters has published a detailed investigation into the massacre of 10 Rohingya men by Myanmar soldiers and villagers, saying that the work led the Myanmar authorities to arrest two of its reporters.

The article, which was published on Friday, describes how soldiers and Buddhist villagers carried out the killings in September and buried the victims in a single grave. Based on eyewitness accounts, it includes photographs of the Rohingya men tied up and kneeling before their execution, and images after their deaths.

Pictures taken later show what appear to be human bone fragments at the site of the mass grave.

Two of the four journalists who worked on the report, U Wa Lone and U Kyaw Soe Oo, were arrested in December and face trial on charges of violating Myanmar’s colonial-era Official Secrets Act. They have been denied bail and face up to 14 years in prison.

The massacre described in the Reuters report occurred during a wave of attacks on the Rohingya Muslim minority in Rakhine State last year that Secretary of State Rex W. Tillerson said “constitutes ethnic cleansing.”
