At least 600,000 people have been stranded in Bangladesh in serious flooding.
The army has been called in to help people trapped by the floods.
Much of the country is under water as a result of the monsoon rains, which have caused the rivers to breach their banks.
The worst-hit areas are the districts of Sirajaganj and Bogra, where 14,000 people have sought shelter in relief centres.
The neighbouring Indian state of Bihar has also been affected by flooding, which has been caused by the monsoon rains of the past weeks.
So far nearly 100 people have been killed and hundreds of thousands made homeless.
