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.

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.
