More than 80,000 people are estimated dead or missing 10 days after the 7.9 magnitude earthquake hit Sichuan province in central China, the government said Thursday, as fears rose that disease, rainy weather and aftershocks could stir more problems.

More than 200 workers repairing quake-shattered roads in China's Sichuan province were buried over the past three days by mudslides, state media reported Monday as millions of Chinese people paused to mark the first week since the deadly quake.
