The U.N. refugee agency says it is worried by reports of people fleeing escalating violence in Myanmar's southern Chin State and Rakhine State, adding to growing instability in these regions, VOA reported.

The U.N. refugee agency says it cannot assess the scale of the current humanitarian situation in these areas because it has little access to these and other regions in Myanmar.

But the UNHCR says reports it has received of the deteriorating security situation in southern Chin State and Rakhine State are very worrying. It says it does not know how many people have fled their homes and have become internally displaced since violence flared up there in December.
