A new video filmed from inside a bus in Trishuli shows dozens of people trying to flee as a flash flood surges down the valley.
The verified video shows floodwaters rapidly swelling and spilling down the river, as many attempt to flee on foot, moped and other vehicles.
Passengers can be heard crying out in alarm on board, as the bus drives along the road which follows the river.
BBC Verify has already confirmed other clips capturing the moment the flood struck the town and revealing its destructive aftermath.

The ministry says those missing were constructing a hydropower plant in the area.

The Nepalese government has sent a helicopter to rescue them, according to the ministry.
A spokesman for Nepal's army says 88 flood survivors have been rescued so far, with troops trying to rescue another 115 from the village of Mailung.
Rajaram Basnet tells the BBC that 15 helicopters have been mobilised for search and rescue operations.
The Ministry of Home Affairs in Nepal says huge loss of life and property is reported in Timure, Syabrubesi and Betrawati.
It says the flood caused damage to the Trishuli hydropower project and swept away bridges in different places.

About 400 tourists - including 291 foreigners - are reportedly missing, the head of Nepal Tourism Board (NTB) tells BBC Nepali.
Most of them were bound for Kailash Mansarovar in Tibet.
"The figure is being updated as reports continue to come in from tour operators running Tibet-bound packages for rescues," says Hikmat Singh Ayer, the board's acting CEO.
Those unaccounted for include more than 100 Indians, 17 Malaysians, 12 Britons, four South Africans, and nationals from the United States, Australia, and the Netherlands.
The flood-affected route also serves as a key gateway to Langtang National Park trekking and Gosainkunda, a holy lake on the lap of mountains, where people pay homage during the Rakshabandhan festival which occurs this Friday.
Nepal police have published a statement saying that 18 people had been confirmed dead by 15:45 local time (10:00 GMT).
One man was found dead in Rasuwa, seven people in Nuwakot, six in Dhading and four in Gorkha, the statement says.
We're now starting to get pictures from Tibet, where CCTV footage captures a wall of mud and water hitting the border checkpoint buildings at Gyirong.
The flash flood and mudslide partially submerged villages in an area popular with trekkers.

The Chinese government has also instructed personnel to go to Tibet - which is controlled by China - for search and rescue missions.
Nepal police tell the BBC that 17 bodies have been discovered in various districts following the floods on Wednesday morning.
As we've been reporting, hundreds are also missing including tourists.

Verified videos from Nepal show a bridge being swept away and multi-storey buildings collapsed by the force of floodwaters, and the aftermath of a town with many buildings destroyed.
BBC Verify has located the clips to the Trishuli Bazaar area of Nuwakot District in Bagmati Province, about 16 miles (25km) to the north-west of Kathmandu.
The video shows the river Trishuli suddenly becoming swollen by enormous amounts of water, which appears to have significantly increased in volume and speed and filled with sediment.
About 40 seconds into the clip, the weight of the flash flood rips the bridge off its supports and carries it swiftly downriver. A few seconds later, several buildings also collapse.
The second verified video, filmed from the same location, shows the devastating aftermath. The river’s level has risen significantly, and trees and many building visible in the earlier video have been ripped away.
It is not clear exactly how many have been destroyed, but many buildings near the riverbank have disappeared, partially collapsed or are caked in sediment from the flood’s force.

Image source, Getty ImagesAn earthquake hit the area at around 08:37 local time, Nepal's foreign minister Shishir Khanal tells parliament, citing preliminary information.
He says the earthquake then triggered an avalanche, which in turn resulted in flash floods. He notes that teams are still verifying the information.
Khanal says that as well as Nepal, China is also experiencing "huge damage".
He says Nepal is co-ordinating with China. So far, 26 police personnel, nine armed police personnel and 44 military personnel are missing.
Officials from customs and immigration are also missing, he adds.
There has also been huge damage on road, bridges, communication and hydropower infrastructures. Rasuwa and Nuwakot were worst affected districts, he adds.
As we’ve reported 384 travellers are "reported missing", including 93 Nepali nationals and 291 foreign nationals.
According to the Nepal Tourism Board, the foreign nationals include:

Yee Liang, a Chinese businessman based in Kathmandu, Nepal, says his logistics company has seven container trucks in the area of the flash flood, which are all staffed by Nepalese employees.
"We have lost contact with all of them. There is no signal, so we cannot reach anyone," he tells the BBC.
Yee says that as far as he knows, there was no warning.
"There were occasional mudslides and landslides, especially in the rainy season, but this one seems much more serious," he adds.
On the Tibetan side, Guan Daoxuan in Sichuan province tells the BBC he lost contact with his wife late on Wednesday morning.
She works for a state-run construction company involved in building roads and bridges in Tibet.
Guan said Nepalese authorities had tried to send a helicopter to inspect the area because road access had been cut off, but strong winds were making it difficult for the aircraft to reach the site.
Hundreds of people are missing following a flash flood in the Bhote Koshi river along the Nepal-Tibet border.
In an update shared on X, the Nepal Tourism Board says it has identified 384 travellers as missing in total, including 291 foreign nationals and 93 Nepali nationals.
It says it is "working to verify" the "whereabouts and safety status" of those travelling through the region.
The flood hit early on Wednesday in Rasuwa, north of Nepal's capital Kathmandu.
