Myanmar's army said on Monday that security forces have discovered a mass grave on the edge of a village in Rakhine State, and have launched an investigation.
A violent crackdown by the security forces in response to attacks by militants in the state has caused around 650,000 Rohingya Muslims to flee to Bangladesh in recent months.
In a statement posted on the Facebook page of the military's commander-in-chief, Senior General Min Aung Hlaing, the army said the unidentified bodies had been found at the cemetery in the village of Inn Din, about 50 km (30 miles) north of state capital Sittwe. It did not say how many bodies were uncovered.
"A preliminary investigation was done by the security forces following a report, by someone who asked not to be named, of people being killed and buried," the army said.
"As a result of the investigations, unidentified bodies were found at the Inn Din village cemetery and a detailed investigation is being conducted to get to the truth,” according to the statement on Facebook, which the army often uses to make announcements.
