An appeal for £190m to help typhoon survivors in the Philippines has been launched.
The UN - which organises relief from governments in different countries - has asked for help for people who are 'absolutely desperate'.
It's thought around 11 million people have been affected by the storm and around 673,000 have lost their homes.
Many are now struggling to survive without food, shelter or clean drinking water.
At least 10,000 people are feared to have been killed by Typhoon Haiyan, which swept through six central Philippine islands on Friday.
People need food
Valerie Amos, the UN's Under-Secretary-General for Humanitarian Affairs and Emergency Relief said the people "need food, they need water, they need shelter. People need to be protected."
She said the UN would work alongside the Philippines government, and that they would focus on getting food, shelter and health supplies to the survivors.
Typhoon Haiyan has been described as one of the most powerful storms on record, bringing winds of up to 200 miles an hour.
The head of charity Red Cross there, Richard Gordon said: "There are an awful lot of casualties... a lot of destruction,"
"It's absolute bedlam right now, but hopefully it will turn out better as more and more supplies get into the area."
He said roads had now been cleared to allow relief workers to get to the hardest hit areas, but that they expected to find many more casualties.
"It's only now that they were able to get in and we're beginning just to bring in the necessary food items... as well as water and other things that they need."
The typhoon has now passed to northern Vietnam, near the Chinese border, where it has weakened to a tropical storm.
Forecasters say heavy rain is likely to hit the Philippines later, which could make the rescue efforts much more difficult.
