At least 6,700 Rohingya Muslims were killed in the first month of a Myanmar army crackdown on rebels in Rakhine state that began in late August, Doctors Without Borders (MSF) said on Thursday.
The figure is the highest estimated death toll yet of violence that erupted on August 25 and triggered a massive refugee crisis, with more than 620,000 Rohingya fleeing Myanmar for Bangladesh in three months.
