Rescue teams and aid pledges have poured into Pakistan from around the world after the devastating earthquake that has killed about 20,000 people.
"We are rushing against the clock here," a spokeswoman for the United Nations (UN) Office for Coordination of Humanitarian Affairs said.
Rescue workers are struggling to pull survivors of Saturday's 7.6 magnitude earthquake from the rubble.
The spokeswoman says an eight-member UN team has begun coordinating the relief effort in the hardest hit areas, and teams from Turkey, China, Britain and Germany are on the ground.
She says the greatest need is for field hospitals, water purification and blankets.
"The logistical problems will be big. We are going to need more helicopters for example."
US, Australia, Japan, the Netherlands, Russia, Saudi Arabia and the United Arab Emirates are among others dispatching help.
The quake, which General Musharraf's spokesman calls the worst devastation in Pakistan's history, has also killed more than 550 people in India and at least one in Afghanistan.
