The U.N. high commissioner for human rights, Zeid Ra’ad al-Hussein, says the Burmese military’s widespread violence against Rohingya Muslims is a “textbook” example of ethnic cleansing. Nearly 300,000 Rohingya have fled to neighboring Bangladesh since last month, as Burmese soldiers have killed and raped civilians and burned down villages. The Burmese government rejected a ceasefire proposed by a Rohingya militant group on Sunday.
