“We wiped out about 20 villages,” Private Zaw Naing Tun said, adding that he, too, dumped bodies in a mass grave. The two soldiers’ video testimony, recorded by a rebel militia, is the first time that members of the Tatmadaw, as Myanmar’s military is known, have openly confessed to taking part in what United Nations officials say was a genocidal campaign against the country’s Rohingya Muslim minority. On Monday, the two men, who fled Myanmar last month, were transported to The Hague, where the International Criminal Court has opened a case examining whether Tatmadaw leaders committed large-scale crimes against the Rohingya.
