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.

More now on the Nepali army’s rescue operation to save about 100 people trapped in a tunnel at a hydropower project swamped by Wednesday’s flooding.

“Two helicopters have been dispatched but it is challenging because it is tough to even locate the entry points of the tunnel,” army spokesperson Raja Ram Basnet told AFP.

Relief efforts are also under way to provide the rescued people what they need.

The army is still working to safely evacuate more than 100 people trapped in the same tunnel.
