The death toll from the earthquake in China's Tibetan region has now exceeded 600 people. But the estimated number of people injured in Wednesday's quake has dropped from 10,000 to 8,000.
Witnesses said survivors spent the night outside in freezing weather and some still bleeding from their wounds, wandered through Jiegu township for a second day.
"We've seen too many bodies and now they're trying to deal with them. The bodies are piled up like a hill. You can see bodies with broken arms and legs and it breaks your heart," said Dawa Cairen, a Tibetan who works for the Christian group the Amity Foundation and was helping in rescue efforts. "You can see a lot of blood. It's flowing like a river."
The quake brought down many buildings, including some schools.
"This feels like a war zone. It's a complete mess. At night, people were crying and shouting. Women were crying for their families," said Ren Yu, general manager of Yushu Hotel in Jiegu, who said he felt at least five aftershocks overnight. "Some of the people have broken legs or arms, but all they can get now is an injection. They were crying in pain."
Rescuers are still searching the rubble of those collapsed buildings for survivors. But the remote location has made it difficult.
Another 5,000 Chinese soldiers, medical workers and rescuers, have now joined the 700 troops already on the ground.
