Chinese state media say an earthquake in southwestern China has killed at least 24 people and injured 150 others.

The official Xinhua news agency says the 5.7-magnitude quake and several subsequent tremors hit Yunnan and Guizhou provinces Friday, damaging more than 20,000 homes in the area. At least 16 aftershocks have been reported.

Television footage showed hundreds of people gathered on streets strewn with fallen bricks and rocks in the town of Yiliang, which appears to have been the worst hit.

The U.S. Geological Survey measured the largest quake at 5.6-magnitude and said it struck at a depth of 10 kilometers.
