Chinese authorities have warned that an artificial lake formed after a catastrophic flash flood hit the China-Nepal border on Wednesday faces a “high risk of breaching and sending flood waters downstream”, according to state media.

“According to forecasts, inflows into the lake could reach about 3 million cubic meters over the next three days amid continued rainfall, increasing the risk of a breach that could send flood waters downstream and potentially cause further damage in areas including Gyirong Port and elsewhere downstream”, state news agency Xinhua reported late on Thursday.

Rescue teams and military helicopters are searching for hundreds of missing people along the mountainous Nepal-Tibet border after the huge torrent of water and mud swept through communities following a glacier collapse on Wednesday.

More than 390 people were killed, authorities in Nepal and China said, and more than 1,400 were missing, including hundreds of foreign citizens and pilgrims.
