United Nations Secretary-General António Guterres has warned the brutal Burmese military operation against Rohingya Muslims is at risk of spiraling into an ethnic cleansing campaign, as the violence against the long persecuted minority group continues. The U.N. says more than than 120,000 Rohingya have fled into neighboring Bangladesh in recent days—with up to 15,000 more expected to flee every single day this week. Advocates say as many as 800 Rohingya civilians, including women and children, have been killed in recent days. This is Rohingya refugee Ansar Ali, speaking after fleeing to Bangladesh.

Ansar Ali: “There was another behind us in which my relatives were there. Suddenly, that sank in the sea as the military started firing at us. Ten members of our family, including my son and grandson, drowned in the sea. We somehow managed to escape.”

More than 300,000 people have signed a petition calling on the Norwegian Nobel Committee to revoke Burma’s leader Aung San Suu Kyi’s peace prize over the violence. Suu Kyi claims the news reports about the military crackdown are “misinformation” and that the security forces are fighting terrorism.
