Myanmarinfo-icon's civilian leader Aung San Suu Kyi and head of the armed forces, Gen Aung Min Hlaing, could potentially face genocide charges in the future, United Nationsinfo-icon human rightsinfo-icon chief Zeid Ra'ad Al Hussein told the BBC.

"Given the scale of the military operation, clearly these would have to be decisions taken at a high enough level," he said. "And then there's the crime of omission. That if it came to your knowledge that this was being committed, and you did nothing to stop it, then you could be culpable as well for that."

In September, Zeid called the treatment of Rohingyas in Myanmar "a textbook example of ethnic cleansing."

He said the situation could not yet be properly assessed because Myanmar had denied access to human rights investigators. Whether genocide has been committed would eventually be determined by a courtinfo-icon, not Zeid.

Suu Kyi has also been criticised by other Nobel laureates, including Malala Yousafzai.
