Police report shortage of relief equipment after magnitude 7.1 quake hits Yushu county in north-west province of Qinghai
At least 400 people have been killed and more have been injured or trapped in rubble after a series of earthquakes in north-west China.
Officials said more than 10,000 people were injured and six quakes hit Yushu county, Qinghai province.
"The need of relief equipment far exceeds supply, including tents, temporary housing, mobile kitchens, power generators. We have reported it to higher levels, who guarantee that relief supplies will be airlifted to Yushu in hours," Xie said. Power and water supplies have been cut although some early reports suggested larger buildings had stood firm. The population is relatively scattered, making it hard to assess damage.
The China Earthquake Networks Centre put the biggest shock at magnitude 7.1, although the US Geological Survey put it at 6.9. The Haiti quake which killed more than 200,000 and left 1m homeless in January was magnitude 7. The China Earthquake Administration said phone lines were down, hindering rescue efforts, while workers were racing to release water from a cracked reservoir.
