Nepal’s search for survivors continues two weeks after deadly floods as families are requested to provide DNA

Authorities appealed on Wednesday for overseas family members of the missing — preferably parents or children — to submit DNA samples via email, two weeks after deadly flooding triggered by a glacial mountain collapse.

A public notice outlined specific types of genetic tests the family members should seek out depending on their sex and relationship to the missing person.

The request comes as Nepali rescuers clung to hopes of finding survivors trapped in hydropower tunnels on Wednesday, and deployed drones to search for bodies in the flood disaster area.

The August 26 tsunami-like surge of water, mud and debris, which began on the China-Nepal border, has killed more than 1410 people and left 5651 missing.

“The rescue and search work in the tunnels at Trishuli 3A, 3B and Chilime hydropower projects is ongoing,” Nepal Army spokesman Raja Ram Basnet said.

There are currently 35 Australians among the missing after one Australian man was located alive on Wednesday.

The majority of the missing Australians were taking part in the annual Kailash Mansarovar pilgrimage which is organised by jointly by the Indian and Chinese Governments.

Authorities in Nepal said 1367 bodies have been recovered and a total of 5132 people remain missing.

In China, 43 people are dead and 519 are missing, according to state media.

Hundreds of foreigners are among the missing, as well as hundreds of hydropower workers.

Three people were rescued from deep inside tunnels — two Nepalis on Friday and a Chinese man on Saturday.

But there has been no official confirmation of further survivors since then.

Thousands of people displaced by the disaster are living in camps, and the charity Save the Children said as many as 540 children had been separated from their parents.

Nepal police said they were taking extra care to ensure the safety of children and women in relief camps.

“We have become more vigilant in temporary holding centres in the affected areas where there are children, women or minority groups who could be victims of sexual abuse,” said Nepal Police spokesman Abi Narayan Kafle.

“We have also started providing psychosocial counselling in different camps,” he said.

While the exact cause of the glacial collapse is unclear, climate change is accelerating glacial melt worldwide and increasing the risk of such disasters.

Mr Kafle said security personnel have involved community members to search for bodies feared buried under debris.

“We have started a special search campaign for missing bodies all across the Bhotekoshi river corridor,” he said.

“We are also using drones to search for bodies.”

Nepal, a largely rural nation of 30 million people that has contributed little to the greenhouse gas emissions driving global warming, has said reconstruction could cost billions of dollars.
