Emergency teams are trying to get food, water and medicine through to the many thousands of people hit by a cyclone in southern and central Bangladesh.
More than 1,000 people died and tens of thousands of homes were damaged.
The teams are determined to get through, even though roads have been blocked by fallen trees and buildings and power lines have gone down.
It's feared that many more people were killed, but the information hasn't got through to officials yet.
The storm destroyed crops as well as homes, and there are concerns that people won't have any money or enough to eat.
'Frightening'
Winds of up to 150mph lashed the country during the storm on Thursday.
"I cannot describe how devastating it was. They were the most frightening five hours of my life," said one witness.
