Refugees rest at night after being evacuated to a high park on a hill in the district of Youxian in Mianyang, Sichuan Province June 9, 2008. 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. REUTERS/Jason Lee (CHINA)
