Rescuers searching for survivors of deadly flash floods on the Nepal-Tibet border have resumed their efforts after suspending operations when a debris dam burst its bank on Friday, increasing the risk of fresh flooding.

Residents in Nepal's Rasuwa district, on the border with Tibet, were seen rushing up hillsides on Friday to escape a possible surge in the river, according to witnesses. Fears of another flood came as authorities in Nepal and China said that at least 543 people had been killed in the disaster.
