Some 647,000 new arrivals of Rohingyas were reported as of December 12, according to IOM Needs and Population Monitoring report released on Wednesday.

The full report and dataset will be available in the coming days.
This report, produced by Inter Sector Coordination Group in collaboration with humanitarian partners, covered the December 8-11 period.
