Nepal flood death toll crosses 1,000, rescuers reach remote areas

The death toll from Nepal's devastating floods surpassed 1,000 on Tuesday as rescuers deployed heavy machinery, helicopters and excavators to reach thousands still missing nearly a week after the Himalayan disaster tore through towns and valleys.

Specialised rescue teams from China, India and Nepal built temporary bridges to reach remote areas and dug through the ruins of hydropower projects in the Himalayas, using excavators to rescue close to 300 workers trapped inside tunnels.

The collapse of a glacier on August 26 sent a deluge of ice, rock and mud sweeping through the impoverished nation's border region with China.

At least 639 people remain stuck in several devastated hydropower stations that have become the focus of rescue efforts, the country's disaster management authority said on Tuesday.

The death toll rose to 1,050, while about 4,000 people remain missing, including 583 foreign nationals.

The disaster left at least 2.2 million tonnes of debris, according to a preliminary estimate by the United Nations Development Programme (UNDP), including parts of buildings, rocks, and sediment.

"The amount of debris shows the scale of the destruction and the challenge communities face as they clear homes, roads and public spaces and begin to rebuild," it said.

More than 11,000 people have been rescued, and power and communication lines were restored in some areas, Prime Minister Balendra Shah said in a social media post on Monday.

"We did not have the time to grab anything before fleeing," said a survivor from the hard-hit Rasuwa district, who had walked to Nuwakot with scores of other survivors.

"What we were wearing is the only pair of clothes we have. And even they are wet from rain."

FOREIGN HELP FLOWS IN

In China, rescue teams worked through the night to reopen access to the Nepali border, on a steep mountain gorge with unstable cliffs on one side and fast-flowing river channels on the other.

Beijing will send DNA testing experts to disaster-hit areas as well as a second batch of relief supplies, its foreign ministry said, adding that equipment would include drones and water purification.

South Korea, nine of whose nationals were working at a hydropower project and are missing, also said it will send a 44-member emergency relief team to support search-and-rescue operations in the Rasuwa region.

Nepal last week turned down foreign involvement in general search and rescue but said it needed specialised services and advanced technological support in areas such as life-detecting machines, large refrigerators and pre-fabricated bridges.

Aid worth more than $42 million had poured into the country after the disaster, Shah said, and the government expected the contributions to increase.

RESCUE EFFORTS FOCUS ON HYDROPOWER STATIONS

Shah said 279 workers had been rescued from hydropower projects, with joint teams from Nepal, India and China working on search-and-rescue operations.

Rescue teams drained water from tunnel heads and used rock breakers to make entry paths into the tunnels, Nepal's army said, as troops tried to reach those still believed to be trapped inside.

"Our first rescue observation at Trishuli Hydro Power plant shows that it is not humanly possible to go into the tunnel," Asish Gurung, a mountain guide helping in the tunnel rescue, told Reuters from Haku village in Rasuwa district.

"We need machines like bulldozers and excavators. There are two of them here now. One is not functioning and the other is being repaired. There may be about 500 people trapped inside," he said.

There has been a boom in hydropower projects in Nepal since the turn of the century as the mountainous country sought to take advantage of its Himalayan water resources to address chronic domestic power shortages and exploit prospects for selling electricity to southern neighbour India.

Prime Minister Shah said the disaster signalled the growing risks the Himalayan region faces from a warming planet.

"The time has come for us to strongly raise before the international community the disasters we are experiencing as a consequence of climate change," Shah said in his post.

Last week's flood was "caused by glacier instability under the long-term effects of global warming", China's state broadcaster said on Monday.
