Myanmar must hold a "proper investigation" into alleged atrocities against the Rohingya, a high-level UN delegation said Tuesday.
The Security Council delegation was the most senior group of international officials to visit Burma's Rakine state since last August, when violence against the Muslims sent more than 700,000 refugees fleeing for their lives into neighboring Bangladesh.
U.S. and U.N. officials call the violence against the Rohingya ethnic cleaning.
British Ambassador to the U.N. said that either Myanmar's government can carry out a probe or it can be referred to the International Criminal Court.
The ambassadors met with top Burmese officials, including leader Aung San Suu Kyi and military chief General Min Aung Hlaing. They talked about making sure conditions are safe for the refugees to return home.
The diplomats asked Burma to sign the memorandum of understanding with the U.N. and Bangladesh for a repatriation that is "safe, voluntary and dignified".
