Britain is trebling the amount of money it's sending to Haiti to help the millions of people affected by last week's earthquake.
It was due to give £6m to the rescue effort in Haiti, which is one of the poorest countries in the world.
But now the government has announced it will provide £20m of aid.
It is feared that up to 200,000 people could have died in the quake, but many more have lost their homes and are in need of supplies and shelter.
At least 70,000 bodies have already been found, and rescuers are still working to pull survivors from the rubble.
In the capital, Port-au-Prince, people are becoming desperate as they wait for aid. Food, water and medicine are all running low and they need tents too.
Supplies have started to arrive and be handed out, but that's caused some violence as people fight over the food and water.
The United Nations (UN) say up to 80-90% of buildings in Leogane, about 12 miles west of Port-au-Prince, have been destroyed.
People have taken refuge in nearby fields and swamps, and many Haitians are trying to leave the ruined capital city, Port-au-Prince.
