Super cyclone Mocha started hitting the coastlines of Bangladesh and Myanmar on Sunday after intensifying into the equivalent of a category-five storm. The powerful cyclone is bringing heavy rain and winds of up to 195 kph, which could see dangerous flooding in areas around the Bay of Bengal.

Storm surges of up to four metres could swamp villages in low-lying areas. There are fears it may hit the world's largest refugee camp, Cox's Bazar, where over one million displaced Muslim Rohingya refugees live in makeshift camps.
