Deadly flooding in parts of India, Nepal and Bangladesh has killed at least 800 people.

They say food and water shortages are a concern as well as the spread of disease.
In Bangladesh at least 115 people have been killed with more than a third of the country underwater.
Damaged infrastructure in some places has made it more difficult for aid workers to deliver supplies to those in need.
In neighboring India, extreme weather hit the state of Bihar particularly hard.
Floods and landslides killed at least 250 people in the state, meanwhile, 13 million have been displaced.
In Nepal the death toll stands at 141.
Monsoon rains hit the region every year, but officials say this year’s rains have been particularly severe and deadly.
