Dozens killed as quake strikes China's western Gansu province Up to 73 people have reportedly been killed after a strong earthquake in China's western Gansu province. The quake hit Minxian and Zhangxian counties, about 170 km southeast of the provincial capital of Lanzhou, the official Xinhua news agency said. Officials fear the death toll could rise as many homes in the affected areas have collapsed or sustained serious damage following subsequent flooding and mudslides. Hundreds of people have been injured and it is unclear how many others are missing as the towns hit lie in remote mountainous regions. As well as providing emergency rescue response, authorities are also having to deal with power outages. Gansu is next to Sichuan province, where a quake of similar magnitude in April killed 164 people and injured six thousands others in China's worst quake in three years.
