At least 367 people have been killed and some 1,300 injured by a magnitude 6.1 earthquake in south-west China, state news agency Xinhua says.
The US Geological Survey said the quake struck about 11km (seven miles) north-west of Wenping in Yunnan province at 16:30 local time (08:30 GMT).
A major rescue and relief operation is under way. State broadcaster CCTV said the earthquake was the strongest to hit the province in 14 years.
Xinhua said about 12,000 homes had collapsed in Ludian, a county of some 439,000 people, north-east of Yunnan province's capital, Kunming.
All of the casualties reported so far are in Qiaojia County of the Zhaotong region, which appeared to be the hardest hit.
