“We have brought some 10,000 Rohingya to safe places after their shelters were hit by heavy rain and landslides,” Hayat told AFP.
At least six Rohingya are among the dead and several others were injured, officials said. The other dead are local villagers whose homes were buried.
Cox’s Bazar district, where more than 850,000 Rohingya refugees are packed into 34 camps, has recorded more than 27 centimetres (10 inches) of rain since Monday, according to weather authorities.
About 7,000 local people outside the camps have also been moved to safety, officials said.
Mohammad Salam, a 30-year-old Rohingya, his wife and three children were among those moved.
“My house collapsed yesterday. I don’t have anything. I have three children and they have started having fevers,” Salam told AFP.
The United Nations refugee agency said 2,500 shelters housing 12,000 Rohingya have been affected by the floods.
“We are also aware of damage to facilities including health centres,” Hannah Macdonald, a UN spokesperson, told AFP.
Aid workers said a coronavirus lockdown in the camps, following a major spike in cases, has affected rescue work as authorities have halted what they consider non-essential visits.
About 740,000 Rohingya fled Rakhine state in Myanmar after security forces launched a clampdown in 2017 that the UN has said may amount to genocide.
Last month two Rohingya refugees were killed in separate landslides during heavy rain.
