Sawt Falasteen - Nepal flood death toll rises as rescuers scour tunnels

In China, 43 people were confirmed dead and 519 missing, according to state media, bringing the overall toll to 1,400 dead and 5,845 missing.

Rescue work continued in Nepal for a 14th day after the devastating glacial and mountain collapse near the China-Nepal border swept away roads, bridges and homes.

Nepali rescuers are focusing on three hydropower projects where they believe workers could still be trapped, the disaster agency said.

Hundreds of hydropower workers are among the missing, but the rescue of three from deep inside tunnels -- two Nepalis on Friday and a Chinese man on Saturday -- has raised hopes that others could still be alive.

"Our search and rescue operation is ongoing," Dharam Raj Uprety, chief of the country's disaster authority, told AFP.

"We are hoping that there might still be survivors in at least three projects, and we are pushing our operations there."

Foreign experts, including from China, India and South Korea, are aiding Nepali teams.

"We have also received reports that there are stranded people higher on the hill," Uprety added.

With mortuaries overflowing, Nepal has buried hundreds of bodies in mass graves after collecting DNA samples for future identification, according to police.

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

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.

David Fisher, of the International Federation of Red Cross and Red Crescent Societies, said reaching communities isolated by the floods was a daunting task because of "narrow and dangerous" access routes.

"Every delay means families wait longer for the support they urgently need," he said in a statement.
