Chinese President Xi Jinping has extended his condolences to his Nepalese counterpart, Ram Chandra Paudel.

"I am confident that the people of both countries will surely join hands to overcome this disaster as soon as possible and rebuild their homes," Xi told Paudel on Friday, China's mission to the UN said.

Chinese state media said earlier that seven deaths have been confirmed and hundreds more are still missing. Here's more on why its hard to gauge the scale of the impact in Tibet.

Authorities in China, which controls Tibet, have warned heavy rain could complicate rescue efforts over the weekend.

The official death toll in Tibet has risen to seven, with 554 people still missing, according to Chinese state media.

The number of people dead is expected to rise significantly as rescue efforts continue.

It's also still unclear whether these figures overlap with those in Nepal, where more than 570 people have died and at least 1,900 are missing.

The dramatic footage was almost impossible to miss. A torrent of water tearing through Gyirong Port, one of the main border crossings between Nepal and Tibet, sweeping away all in its path as hundreds of people fled for their lives.

The scenes, captured by CCTV cameras, quickly spread on social media and onto screens around the world.

Except here, in China.

Only a single still-frame shot has been broadcast so far by the country's state-run flagship news bulletin.

It has also been difficult to find the video on China's heavily censored internet. It is just as hard to even find posts describing the flash flooding that has claimed hundreds of lives, with just as many still unaccounted for since Wednesday.

Beijing has launched a massive rescue operation involving hundreds of emergency workers, which is continuing, and President Xi Jinping chaired an emergency meeting with officials to co-ordinate efforts.

But when you compare the country's internet content to what much of the world has been seeing online these past few days, China's firewall becomes more visible than ever.

European Commission President Ursula von der Leyen has announced Europe is committing €2m (£1.7m) in immediate humanitarian aid for Nepal, saying the support will deliver "life-saving assistance to families and communities hit hardest".

The US embassy in Nepal also says it sent an initial shipment of emergency supplies, including more than 2.5 tonnes of food and supplies for two schools being used as shelters in Rasuwa.

Canada's minister of foreign affairs has announced C$5m (£2.7m) of support and New Zealand says it will contribute NZ$1m (£436,800) to the Nepal Red Cross Society and another NZ$1m to other aid groups.

India's external affairs minister says a third flight carrying 10 tonnes of humanitarian assistance has left the country, while 11 doctors, paramedics and a reconnaissance team for tunnel rescue operations have also been sent.

The International Federation of Red Cross and Red Crescent Societies said earlier it had mobilised "its entire global network", having also launched an emergency appeal for CHF 25m (£23m; $31m) to support the "immediate lifesaving response".

It's now 03:30 in Nepal and 5:45 in Tibet - almost three full days since floods first hit the area on Wednesday morning. Here's the latest:

Death toll rises

• In Nepal, more than 570 are known to have died and at least 1,900 are missing, the disaster relief agency says
• In Tibet, at least five people have been killed and more than 550 are missing, Chinese state media reports. It's not clear if there are any overlap in these figures

Challenging rescue efforts

• Nepali officials say that around 4,000 people have been rescued there. Separately the tourism board reports that more than 100 tourists have been found
• But the destruction of key infrastructure like roads and bridges is making reaching the worst-hit areas incredibly challenging. Heavy rain since the flash floods has added to the challenge

Fears of a second flood

• China temporarily paused rescue efforts over fears that a lake - which formed in the aftermath of Wednesday's flooding - could burst, triggering further flooding.
• Searches have since resumed, but the Chinese military has warned more rain forecast over the weekend could further complicate rescue efforts and "mudslides may occur in some areas".

George Graham of Save The Children UK says the charity's team in Nepal has been "working flat out" to rescue children, many of whom are stranded without their parents.

He tells the BBC News channel there are around "fifty children that we know of who are trapped in schools" who "may or may not have clean drinking water".

"The bridges that connect those schools to the roads have been washed away. The race is on to try and find those kids," he says.

"The flood came at the start of the school day," he says. "These children walk a long way from their homes to go to school, completely separate from their families."

Graham says they have rescued nine children so far who "walked a long way until they found our relief teams".

"They found themselves alone.. having to work out how to stay alive and stay safe," he says. The next job is working to reunite them with their families.

But there are "hundreds and hundreds of kids in this situation", he says.

We can now bring you more on ongoing rescue efforts taking place near Gyirong Port, located on the Nepal-Tibet border.

China's state broadcaster CCTV reports six personnel from the Tibet fire and rescue service as well as 15 people and a dog from the Sichuan fire and rescue service arrived at the site approximately 16:30 local time (09:30 BST) on Friday.

"There was no road... it was all virgin forest and sheer cliffs," rescue worker Zou Mingqi tells Reuters, adding: "As far as the eye could see, there was nothing but ruins."

CCTV says rescue teams traversed dense forest and canyons to approach the area.

China's armed forces earlier said heavy rain scheduled to continue in Gyirong county over the weekend means "mudslides may occur in some areas".

We've continued to hear stories of loss and devastation today as relatives of those caught up in the disaster await news, and rescuers and healthcare professionals continue their response work.

These are some of the stories we've heard:

• At a rescue centre in Nepal, a woman cradling a crying child told the BBC her father, husband and mother all went missing in the floods
• Vikram Kolagatla, who is trying to find out if his wife Geetha Reddy survived the floods, said: "We’re not sure what to do. I have two little girls... [they] still don’t believe it"
• "I haven't seen this kind of disaster in my life," Nepalese army spokesperson Brigadier General Rajaram Basnet said

• Naresh Goyal, whose sister is among the British nationals missing, said it was her sister's dream to travel to Nepal and take part in the Kailash Mansarovar Yatra pilgrimage
• A doctor in Kathmandu told the BBC he treated an eight-year-old boy who had been at school when the floods hit - the rest of his family at home were swept away

• Aid worker Dhruba Gurmachhan said the situation on the ground in Nepal is "chaos" but says "there is hope" that some still missing could be found alive

Among the sheer devastation caused by the floods, Nepalis are banding together to pull their communities through.

Over the past day or so, I've have spoken remotely to a number of people supporting those in need, but one story has stuck with me in particular.

Rabi, a resident of capital city Kathmandu, tried to get as close to the affected areas as possible in order to deliver food and medicines.

He spoke to me about providing help to a woman who was already homeless and living in a tent before the flood hit. Rabi recalled how she cried and pleaded with him for any kind of assistance. He then provided some food and medicines to her.

And then there's Tashi, a wildlife filmmaker from Mustang in north-west Nepal who was travelling to and from Kathmandu. He was asked by authorities to use his drones to help map the disaster zone and use thermal imaging to find any trapped people.

"We saw that the entire town of Timure was completely covered by mud and debri," Tashi who travelled from Kathmandu said.

"We saw there were six to seven houses remaining that were on the hillside."

Although Tashi was able to help the authorities gauge the extent of the devastation, he was unable to detect any individuals in need of rescue.

This is because he regularly had to move his drone at the path of rescue helicopters. The rainy conditions and mountainous landscape also made the task difficult.

The UK government is deploying a rapid deployment team to Nepal to assist those affected by the flash flooding, Ed Miliband has announced.

The foreign secretary says the team will work alongside British embassy staff and local authorities, adding that Foreign Office teams will "continue to work around the clock to support British nationals and their loved ones".

He urges Brits in Nepal or China who require consular assistance to contact the British embassy in their respective country or call the FCDO hotline.

Indian authorities say they have recovered seven bodies from rivers flowing from Nepal, believed to be victims of the deadly flash flooding.

The bodies were found floating in rivers in the Maharajganj and Kushinagar districts of Uttar Pradesh state, which borders Nepal's southern flood-hit Chitwan region, an official tells the AFP news agency.

"Four unidentified bodies were recovered in the district on Thursday," Maharajganj district magistrate Gaurav Singh Sogarwal says.

"We think they have been swept into India from Nepal following flash floods there."

Three more bodies were recovered in Kushinagar district, around 70 kilometres (43 miles) downstream from the frontier, a police official also told the news agency.

Authorities are working to identify the bodies.

Tanay Ranjan has not heard from his older brother, Ankit Ranjan, and sister-in-law, Ankita Chandra, since Wednesday when the pair were at the Nepal-Tibet border area of Rasuwagadhi while on a pilgrimage.

He says their whole group is missing and the last message he and his mother received from Ankit was at 07:45 on Wednesday to say they had reached the immigration area.

"We don't know if they crossed the border," he tells the BBC.

He adds: "We don't have a clue where they are. We are very much devasted."

Prajval Haldia says he can remember dropping his parents Pavan and Kavita off at the airport for their trip to Kathmandu, spending a few days sightseeing before moving on to Mount Kailash.

He is speaking from the south London Sanatan Mandir temple, where 16 people from the community have been missing since Wednesday.

The group have been meeting daily since the disaster struck, with some expressing a desire to travel to join the search and rescue effort.

Prajval tells the BBC: "Everyone here is in the same position and that's really helping."

The son says he is trying to stay positive, adding "no news is good news", and that he has been in contact with the Foreign Office and his local MP.

"Obviously it's a very difficult time. There's ups and downs when you think about certain things, but we're just hoping and really praying that everything's ok and they are going to be back soon," he says.

A UK foreign office minister says he has had a "very constructive meeting" with the acting Nepalese ambassador to the UK to discuss the "shocking and catastrophic situation" in Nepal.

Stephen Doughty says he told the ambassador the UK "would stand by Nepal in their time of need".

He adds that while the number of Brits missing in the region has been cited as 33 by Nepalese authorities, this number may "fluctuate".

Doughty says: "This is a very, very complex situation, very remote areas and you'll have seen the scale of the devastation."

I’ve been speaking to a consultant from the National Trauma Centre in Kathmandu, Nepal.

In the last 48 hours, his department has received a number of the survivors from these deadly floods. He told me that 38 injured people have been admitted - and the majority of these have been transported from the Trishuli area.

"Most of the injuries are minor injuries because these were people who were able to escape, however there are some who were pulled into the flood waters."

"They were pushed to the outer edges of the torrent which is how they were able to survive… they were literally thrown away," he adds.

He says the patients that he has been treating have "suffered various injuries to the chest, abdomen, face and legs". They had mainly experienced impacts from pieces of wood and the mud waters.

He tells me about one story that he found particularly heartbreaking. An eight-year-old boy had been admitted to the hospital with minor injuries. He survived because he had been at school at the time of the floods, but the rest of his family at home had been swept away.

China's armed forces has said heavy rain over the weekend could complicate rescue efforts, as "mudslides may occur in some areas".

In a post on X, it says rescue efforts have been taking place near Gyirong Port.

Gyirong is the largest land border crossing between Tibet and Nepal.

The "steep terrain and narrow valleys" have made rescue operations "extremely difficult", the Chinese armed forces' account writes, adding "frequent rain" in the area is forecast until Sunday.

The army says "the main challenges" are unstable terrain, damaged roads, poor weather and disrupted communications.

The scale of the destruction along Nepal’s Trishuli River has been revealed in new satellite imagery reviewed by BBC Verify.

Among the worst-hit locations is the Nepal-Tibet border crossing, where the moment was captured on CCTV on Wednesday when the area was engulfed by a huge surge of floodwater.

The satellite imagery from US-based intelligence firm Vantor shows the site has been almost entirely washed away. It also shows how the flood was powerful enough to force water and debris uphill to the west of the crossing.

Damage and mud can be seen more than 2.5km (1.5 miles) upstream, some of it more than 100m (330ft) above the normal level of the river.

The Vantor images also show hydroelectric dams and large areas of villages downstream have been wiped out, leaving only mud and debris behind.

It's just past 22:00 in Nepal and past midnight in Tibet - a bit more than 60 hours since the floods hit.

Here's a look at some of the latest developments:

• The number of people missing in Nepal has risen to nearly 2,000, according to the country's disaster relief agency
• It says 517 foreign nationals are among them. As is not uncommon shortly after a major disaster, different figures have emerged - Nepalese police earlier said 575 foreign nationals, including 33 Brits, were among those missing

• The death toll in Nepal has also risen to 579, the disaster relief agency says
• In Tibet, five people have died and more than 550 are missing, Chinese state media says, but it is not clear if these numbers overlap with Nepal's. Here's more on why its hard to gauge the scale of the impact in Tibet
• Chinese officials are monitoring a barrier lake that formed following the landslide - it temporarily suspended search efforts earlier over fears there could be a breach, releasing more water. Rescue efforts have since resumed

• Families across the world remain in limbo as they await news - Anant Patel from Coventry told the BBC he's trying to "stay strong" as he waits for news of his parents, who were on a pilgrimage in the area

Anant Patel, 29, from Coventry, is nervously waiting for word of his missing parents, Bipin and Mala.

The pair travelled from Coventry on a pilgrimage, and Anant believes they crossed into Tibet from Nepal moments before the flood hit the Gyirong border crossing.

"It’s a difficult situation for us all, and we are doing our best to stay strong as best as we can in the circumstances," Anant says.

Anant has been in contact with the UK's Foreign Office, but he and his 27-year-old brother, Deepesh, are concerned about the length of time they may have to wait for information.

Bipin and Mala are among several pilgrims who were in the region when the floods hit.

The area around the Nepal-Tibet border is a popular site for Hindus and Buddhists - tens of thousands visit on trips to sacred sites each year.

Dramatic videos from Bidur in Nepal have emerged which show people sheltering in a building which remained standing despite being battered by a torrent of floodwater which gutted or washed away much of the town.

The first video from Wednesday, confirmed by BBC Verify, shows the building somehow withstanding surging floodwater and violent waves while people desperately take shelter within it, during the peak of the flash floods.

Debris from other buildings, and vehicles caught up in the torrent can also be seen colliding with the building, which had become surrounded on all sides by floodwater.

The second video shows how the green house remained virtually intact despite the devastation brought upond the surrounding area, around 45km (28 miles) from the start of the flood.

In the verified clip, a group of survivors can be seen standing on its balcony after the floodwater had receded leaving mud and debris behind. One person can also been seen on the roof waving a red cloth, seemingly calling for help.
