I have just spoken to Sonam Dorjee, a trekking guide for international tourists who lives in the village of Rasuwa Syafru Besi in Nepal's Rasuwa district.

Sonam says his village was hit by the flood at 09:00 local time (04:00 BST). Luckily, Sonam had left an hour earlier to drive to Kathmandu for a planned visit.

But his sister, Dechen Tamang, is missing, along with her husband and several other family members.

Sonam says he heard sounds of the floods as he drove away from the village.

"It sounds like an earthquake," he says. "My house has collapsed... I have seen a photo."

He describes the flood as "sudden and devastating".

"Many survivors are now left without homes and they need emergency rescue and evacuation, as well as food, temporary accommodation and medical support."

He is praying his sister may be found alive. “There is a 10% chance we hope," he says.

It’s difficult to say exactly what has caused the flooding at this early stage, but some details are starting to emerge.

“Most people think of flash floods as being caused by heavy rainfall, but in Nepal and Tibet, as in many other high-mountain regions, they can also result from complex chains of hazards,” says Prof Liz Stephens of the University of Reading.

The working theory in this case is that an ice avalanche was the trigger.

Large volumes of ice and rock would have added to the water already in the river and could have generated a sudden surge in river levels.

The avalanche could also have temporarily blocked the river at a narrow section, creating a dam and allowing water to build up behind it.

When the dam fails “it can cause a sudden, devastating release of water and sediment downstream,” Prof Stephens says.

An earthquake was also recorded in the region at a similar time to the floods.

It’s not yet clear what role that played and whether it triggered the avalanche itself or released water that had already been trapped behind the landslide dam.

The BBC has been hearing from survivors of the flash flood.

"My family members were swept away by the flood in front of my eyes," says Kalpana Malla from Nepal's Nuwakot district.

She says her father, mother, sister and her sister's children were all swept away.

"They could not escape the flood; there was no chance at all," she says. "This flood took everything, but my son and I climbed the rooftop of a house and survived but couldn’t explain how."

Her son, Sugam Malla, says he saved his mother by pulling her hand.

"Before that I had given my phone to my sister to remain safe and contact for help, but she is not reachable now, the mobile is switched off. I am worried she must be swept away."

Another woman, Goma Pandit, says she has lost her buffaloes and all her other cattle.

"My farmland is also swept away. Ten sacks of mustard seeds, tons of corn and rice paddy are all gone. Nothing is left."

These images, taken from footage shared by Nepal police, show the scale of the flash flooding in Nepal.

The authorities don't specify where specifically in Nepal the footage shows.

Police shared the video as part of an update on social media in which they asked members of the public to help each other, and to ignore rumours.

Officials in the Bihar state of India, to the south of Nepal, are warning residents to remain alert amid warnings of flooding from the Gandak river.

Samrat Choudhary, the chief minister of Bahar, says that measures such as the monitoring of embankments, night patrolling and deployment of emergency personnel teams have been put in place in several of the state's districts.

The Red Cross - which is warning of waves potentially three metre high waves - says that preparations have intensified in the area since officials met earlier today, and that emergency teams are being deployed to three districts in the state.

The teams have prepared a plan for evacuation if required.

The Chinese air force has managed to launch a drone above the Tibetan border town of Gyirong to survey the area hit by a landslide, report state media.

Dramatic footage appears to show the border being struck by a devastating wave of water and mud.

Chinese state media say the People’s Liberation Army has activated its emergency response plan and has begun planning more aerial reconnaissance and airlift missions.

Transport aircraft, helicopters and drones are also on standby.

Verified videos of the flash floods show two different bridges over the Trishuli river breaking in half after being struck by debris from other bridges swept away further upstream.

BBC Verify has identified one clip as showing Ghatbesi bridge, which is more than 17 miles (27km) to the west and downriver of the videos from Trishuli town we reported on earlier.

The debris, which includes sections of another bridge, smashes into Ghatbesi bridge, splitting it in two before the flood carries it downstream.

The second video shows the Dhadingbesi bridge, about 4 miles (6km) further to the west downstream of Ghatbesi, also being struck by violent floodwaters carrying the remains of a bridge.

The office of Nepal's prime minister has just confirmed that 95 bodies have been recovered so far.

We reported that figure from Nepal police a short time ago - with rescue and recovery efforts ongoing.

Four hundred and three people are still missing, including 62 Nepalese people and 341 foreign nationals, says the Nepal Tourism Board in its latest update.

It says that 200 of the missing are women and 203 are men.

The foreign nationals are understood to come from 26 different countries.

From India, 133 are missing, while there are 47 missing from the US, and 33 people from the UK.

According to the tourism board, which cited tour operators, most of the passengers were on their way to Mansarovar, near the border of India and Nepal.

Nepal police have published a list of some of the flood victims receiving treatment in various hospitals.

Details for 29 people are provided, including a baby of just three months old, said to be in a "normal" condition.

Two three-year-olds and teens as young as 12 and 14 are also listed. It is unclear how many have been injured and are in hospital overall.

The list includes injury details, with some patients said to have bruises or scratches "all over the body" and others with head injuries. Several are reported "unable to speak".

Nepal police say the death toll from the floods has risen to 95, according to AFP and Reuters.

This is up from the 31 deaths reported by authorities just a few hours ago.

Nepal is a popular destination for mountaineers and trekkers, and Hindu and Buddhist pilgrims. Thousands of people visit Nepal each year to offer prayers at religious sites.

This is also a busy season for those visiting Mount Kailash, located in the Ngari prefecture of Tibet, which is controlled by China. It’s a 10-day trip from Kathmandu. Thousands cross the Nepal border into Tibet to see these holy places.

Now Nepal Tourism officials say hundreds of these pilgrims, including more than 100 Indians, are missing. The Nepal-Tibet border point at Gyirong - which was hit by a wall of mud and water - is a popular border crossing for the pilgrims.

A tour operator in India’s southern state of Tamil Nadu said his clients travelled on three buses in the mountainous region. One of his colleagues said that when there was a massive landslide they tried to escape from the area but one of the buses fell from the road and they were waiting for information on the passengers.

He said the Nepalese army had been assisting in the search and rescue operation. More than 40 people from the state are reported to be unaccounted for.

The embassies in Nepal of the UK, Australia, Finland, France, Norway, Switzerland, and the EU are encouraging their citizens in the areas affected by flooding to "follow the guidance of local authorities and official safety advisories".

"We are deeply saddened by the devastating flooding in Rasuwa and Nuwakot districts and surrounding areas," they say in a joint statement.

"Our thoughts are with all those affected by this disaster. We express our solidarity with the people of Nepal during this difficult time."

Nepal police say 114 people have been rescued in the area of the Bhotekoshi river in Rasuwa, where the floods hit on Wednesday, according to local media.

The Nepalese army has rescued more than 80 people through various flights, while 29 have been rescued though various private helicopter companies, Nepal TV and Radio Nepal report.

We reported earlier that 12 British nationals were among the approximately 400 missing tourists.

A tour company now confirms a dozen Britons are missing from one of its excursions across the Nepal-Tibet border.

Ram Kumar Adhikari, manager of Alpine Eco Trek, tells the Press Association (PA) there is "not much info to share at the moment, but yes we have 12 British citizens [supposed] to make entry this morning".

The ages of the missing Britons range from 13 to 65, PA reports, citing travel logs.

Two Irish nationals and four South African nationals were also on the excursion and are believed missing, Adhikari says.

The US embassy in Nepal says it is working to account for citizens who may have been affected by the disaster.

At least three US citizens are known to be missing following the deadly flash flood.

The embassy is urging Americans to avoid the affected area.

As emergency personnel work to find survivors, more pictures are coming in that reveal the extent of the damage in Nepal's Nuwakot district.

Nepalese Foreign Minister Shishir Khanal says there is a still a risk in coastal Nuwakot, and is asking residents to say on high alert.

Residental blocks and cars can be seen submerged in mud and water, some almost entirely.
