Rescue teams have been working around the clock to try to find survivors of the massive earthquake which struck Pakistan on Saturday.
More than 20,000 people are thought to have died in the quake, which has made hundreds of thousands of others homeless and wiped out communities.
Many people from Britain are flying out to check their family and friends are all right and to help the rescue teams.
Several aid appeals have been set up to help the survivors of the disaster.
Pakistan's president Pervez Musharraf said: "We need relief goods in the form of tents and blankets and medicines."
It's estimated that 11,000 people died in the city of Muzaffarabad in Kashmir.
The school day had just started when the earthquake struck and it's feared that many children are among the dead.
Heavy rain and landslides have made it difficult for rescuers to get to some areas.
The quake, measuring 7.6 on the Richter scale, is thought to be the biggest to strike the area for a century.
