The US government investigates the allegations of atrocities against the Muslim Rohingya minority and collects materials that could be used to prosecute the country's military for crimes against humanity.
Under the leadership of the State Department, the investigation revealed more than 1,000 interviews with Rohingya men and women in eviction camps in Bangladesh, which investigated allegations of extrajudicial killings, rape and arson by Myanmar's security forces.
"The purpose of this research is to contribute to justice processes, including raising public awareness, international advocacy efforts and community-based reconciliation efforts, as well as possible investigations, truth-seeking efforts, or other efforts to promote justice and accountability," read a document used by the investigators and quoted by Reuters.
The investigation is modeled after a similar exploratory in Sudan's Darfur region in 2004 that paved the way for the US to call the violence a genocide and impose sanctions on the Sudanese government, according to Reuters
: Rohingya Refugees: Myanmar's Crisis is Bangladesh's Burden
Almost 700,000 Rohingya have fled across the border into Bangladesh since August when militant Rohingya attacks unleashed army reprisals. Former Secretary of State Rex Tillerson said last year that the subsequent crackdown would be "ethnic cleansing". The UN Human Rights Commissioner for Myanmar said the violence carries "the hallmarks of genocide".
But the opinions in the State Department are different legal to classify the crisis. In December, the US passed sanctions on a Burmese general who oversaw the western region of the country during the violence.
