Rescue workers are still struggling to reach remote areas near the epicenter of an earthquake that struck Yunnan province on Tuesday night.

The magnitude-6.6 quake killed at least one person and injured more than 300. Casualties were reported mainly in Jinggu county, the epicenter. Ten townships were hit in the county, seven reservoirs damaged and more than 124,000 people affected.

Ma Jiangtao, a 55-year-old villager from Qiaotou in Yongping township, complained that no rescue aid had arrived at the scene.
