BEIJING (AP) — Survivors of a series of earthquakes that killed 81 people and injured more than 800 in a mountainous area of southwestern China were desperately waiting for more aid to arrive Sunday as jolting aftershocks kept fears high and hindered rescue efforts.

The latest victim was a 2-year-old child who was hit by a falling wall as an aftershock struck Saturday night, the state-run Xinhua News Agency reported.

The first earthquakes struck Friday in a region of small farms and mines near the border between Guizhou and Yunnan provinces, where some of China's poorest people live.
