More than 1,400 people are missing and at least 552 have been killed after a devastating, tsunami-like wall of water gouged a path through the border region between Nepal and Tibet, sweeping away entire villages.
Here are the latest developments after Wednesday's disaster:
The level of trauma cascading from the Nepal flash floods is "enormous", the Red Cross said Friday, with early estimates suggesting 93,000 people may have been affected and that the death toll will continue to rise.
"Due to roads and bridges having been washed out and both cell coverage and electricity cuts, we have not yet been able to access some of the hardest-hit areas," said David Fisher, International Federation of Red Cross and Red Crescent Societies head of delegation for Nepal. "The trauma of this event is enormous."
Rescuers in the autonomous Chinese region of Tibet have reached the main area wiped out by the devastating mudslide, Chinese state media reported.
"At approximately 4:30 pm (0830 GMT) on 28 August, six members of the first response team from the Fire and Rescue Corps of Tibet and 15 members and one dog from the first response team of the Fire and Rescue Corps of Sichuan arrived at the border area... They are the first professional teams to reach the core rescue site," Xinhua news agency reported.
Nepal's police announced a new death toll of at least 547 people. Chinese state media has confirmed at least five dead on the Tibet side, taking the total overall to 552.
More than 1,400 people are missing in total on both sides of the border, including hundreds of foreigners.
Nepal issued a warning to move to higher ground after a dam in Tibet was reported to have burst.
China also halted rescue efforts, with state media saying a lake formed by immense piles of debris had begun overflowing. State media later said the risk from that lake was "decreasing" and rescue operations were proceeding "in an orderly manner".
It was not immediately clear if the lake was the same as the dam that Nepalese authorities warned had burst.
Nepal appealed Friday for international financial assistance, but said it was coping without foreign rescue teams.
"It is not that we will not need help, but our security network is capable and working effectively right now," foreign ministry spokesman Lok Bahadur Chhetri told AFP. "If Nepal needs any specialised help or expertise, then we will request it."
Chinese President Xi Jinping offered Beijing's help Friday.
Rescuers have evacuated 555 stranded tourists from Tibet, Chinese state media reported.
CCTV said that 499 residents and 555 tourists had been transported out of the disaster zone as of Friday morning. It did not specify the tourists' nationalities.
The Nepali military has located people trapped in the tunnel of Trishuli 3A hydropower project, where they were working to bring out survivors.
"Two helicopters have been dispatched but it is challenging because it is tough to even locate the entry points of the tunnel," army spokesman Raja Ram Basnet told AFP.
Some 350 workers and residents have been brought to safety from the site, he added, but there were more than 100 people trapped in the same area.
In India, authorities said they had recovered seven bodies from rivers flowing from Nepal, believed to be flood victims.
