A magnitude 6.6 earthquake has hit south-western China, killing at least 192 people and injuring thousands.

The Chinese seismological bureau initially measured the quake at magnitude 7. Strong jolts toppled buildings at 8am local time, sending people into the streets in their underwear and wrapped in blankets.

6,000 troops have been dispatched to assist in clearing the area and helping rescue efforts.

Lushan, where the quake struck, is home to 1.5 million people. Known for its mountains, the area is near a well-known preserve for pandas.

The quake struck near the area where another devastating earthquake left 90,000 dead or missing and presumed dead in 2008.

17:22 GMT: Power supply has been partly restored in Chinese counties isolated by the earthquake, Xinhua reported. The counties where electricity has returned include Lushan, with emergency teams also starting to put the power network back in use in Baoxing and Tianquan, CCTVNews said. In those parts of China, particularly in remote mountainous areas, people spent at least 33 hours in isolation after the quake left them without food, water or shelter.

Earlier the Chinese Foreign Ministry thanked foreign governments for offers of help, but said the country was able to cope with the situation on its own.

“Taking into account the road situation and the [disruption of] telecommunications in the area affected by the earthquake, foreign rescue and medical teams, as well as humanitarian help, are not needed at the moment,” a spokesman said.
