• Some 2,000 troops have been sent to the Zipingku Dam above Dujiangyan over fears for its stability. The official Xinhua news agency quoted the Ministry of Water Resources as calling for the dam to be protected, as surrounding area would be "swamped" if it collapsed
• More than 1,000 staff and students are trapped in a Juyuan Middle School, in a township of Dujiangyan. Bodies are reported to be stretched out in the playground as parents wait for news. One girl has been pulled out alive
The BBC's Dan Griffiths at Juyuan school says rescue workers have been bringing out the bodies of children all day as hundreds of relatives weep:
"The school at Juyuan is a pile of rubble and twisted metal. Hundreds of distraught relatives are crowded round the entrance waiting for news about the children, many of them in tears... Rescue teams are using cranes, but progress has been slow and hampered by heavy rain overnight. The bodies of those already found lie in a corner of the playground. The signs of the earthquake are everywhere here - buildings collapsed, many places without electricity or water, people living in makeshift tents, their possessions scattered around them."
