Thousands of people have been displaced within the Rohingya refugee camps in Bangladesh over the last few days after heavy monsoon rains started last Thursday causing flooding and landslides.
According to the World Food Programme charity, at least one person is also believed to have died.
WFP has assisted 11,000 refugees affected by the severe weather providing emergency packages of food.
The severe weather is expected to continue until at least next Tuesday.
Nearly 700,000 Rohingya Muslims have fled across the border from Myanmar since August 2017 when the Myanmar military launched a violent crackdown in Northern Rakhine State.
