Millions of people have been left homeless after large tidal waves struck the two countries
Cyclone Aila is causing widespread damage along the coast. Rising flood waters there are forcing thousands of residents from their homes.
Floods ravaged coastal parts of Bangladesh Monday the 25th, leaving thousands of families homeless.
Those fortunate enough to escape the rising flood waters walked to temporary shelters, while others were left stranded.
"The water from the sea entered our village and flooded our homes. All our houses were flooded. No dry place remains."
The storm surge from Aila washed away dozens of shrimp farms and flooded rice fields.
With Aila tracking towards the coast the Bangladesh Weather Bureau has kept storm warning in place for the ports at Chittagong, Mongla and Cox's Bazar.
Almost 40 have perished in Bangladesh.
This poor south Asian country is battered by storms every year.
A cyclone in November 2007 ravaged a large part of the country's coast, killing nearly 3,500 people and displacing around two million.
