Aftershocks hit brimming China quake lake

CHENGDU, China (Reuters) - Chinese troops are carving a third drainage channel into the unstable dam holding back a big "quake lake", as water levels rise and aftershocks send more debris tumbling into the water, state media reported on Monday.

Soldiers are also using short-range missiles and dynamite to blast apart boulders blocking the first channel, to speed up the flow of water, the official Xinhua agency said.
