Latest news: A Chinese military helicopter involved in relief operations (救助工作) crashed in heavy fog

dammed by landslides caused by the earthquake. The risk of a bursting barrier dam near the town of

Tangjiashan threateds millions of people who live downstream, and the authorities have been working feverishly

in recent days to evacuate (疏散) hundreds of thousands of residents of the river's watershed area even as

they try to prevent a flood.

It was not clear from initial reports whether the crashed helicopter was involved in this operation. Xinhua

reported that the aircraft had encountered "strong air currents" prior to the accident.
