Officials in Bangladesh say floods triggered by monsoon rains in the country's south have killed at least four people and displaced more than 10,000.

Authorities say at least 200 villages have been flooded. The district of Cox's Bazar was one of the worst affected.

Officials say the displaced have taken shelter in schools, with local officials handing out relief supplies to those in need.

Monsoon floods hit Bangladesh nearly every year. South Asia's monsoon season runs from June to September and is vital to millions of farmers who rely on the rains to irrigate their land.
