Another strong aftershock has rattled China's quake-devastated Sichuan province amid increased concerns about lake floodwaters, reports AP. There were no immediate reports of deaths or injuries from the 5.3 tremblor, which came as authorities began evacuating people downstream from a lake formed by last month's quake. The water level in the "quake lake" is rising, putting over a million survivors at risk from flooding. (More China stories.)
