A strong earthquake has hit northwestern China, killing at least 11 people and toppling hundreds of buildings.
Chinese seismologists say the 6.1 magnitude quake hit in the sparsely populated Zhaosu county in northwestern Xinjiang province.
The affected area is in a mountainous region along China's border with Kazakhstan.
Officials say scores of people were injured and hundreds of those who were left homeless are camping outdoors in sub-zero temperatures.
An official with the Xinjiang Seismological Bureau says rescue teams are in the area where he says homes, office buildings, and schools have collapsed.
The government news agency, Xinhua, says some of the victims and homeless were workers of the Xinjiang Production and Construction Corps, a civilian construction and militia unit.
Reports from the scene say many of the buildings that toppled were older buildings that were put up 30 or 40 years ago.
Xinjiang province has been hit often by strong earthquakes. In February, a magnitude 6.8 tremor killed at least 268 people and injured thousands.
Reports from neighboring Kazakhstan say Monday's shaking was felt as far away as the Kazakh capital, Almaty.
