Richard Irvine-BrownBBC Verify journalist BBC Verify has verified two photos showing lit sparklers attached to bottles inside Le Constellation nightclub in the ski resort of Crans-Montana, Switzerland, shared online with claims they were taken around the start of the fire on New Year's Eve. One image shows people holding several bottles in the air with lit sparklers attached and what appears to be a fire on the ceiling. We searched for previous versions of this image online and no copies existed before yesterday. There are several details in the photograph which match older photos of the interior of the nightclub, including the bar, the wall decor and the pipework. We ran the photo through four AI-detection tools, none of which detected AI manipulation but one said the image had been edited. Running it through a digital manipulation tool showed no evidence of manipulation. The second image we looked at shows someone in a sleeveless black dress and crash helmet holding a bottle with a lit sparkler attached, on the shoulders of someone wearing a mask. We searched for previous versions online and no copies existed before yesterday. Parts of a neon sign for Le Constel can be seen in the background, consistent with older photos from the club. The image has been run through three AI detection tools, none of which detected AI manipulation but one said the photo was edited. Running it through a digital manipulation tool showed no evidence of manipulation. Sarah RainsfordReporting from Crans-Montana One of the most striking details of this tragedy is how young the victims are. Many of the dead and injured are teenagers. Le Constellation was popular with a young crowd, both tourists and those working the ski season here, and locals. The drinking age here is 16, it was New Year’s Eve - and they were partying. Now, more than a day later, distressed parents are still searching for their children. And young people who survived are describing horrific scenes they saw and can never forget. Six Italians are still missing, all teenagers. The mother of Giovanni Tamburi, from Genova, has made a public appeal on social media for help to trace him. The last she heard was a New Year’s message around midnight, since then he hasn’t answered his phone. He was with friends, who escaped the fire. But Giovanni’s mother has called around all the hospitals and there’s still no sign of him. Ilan Achour, 26, works in a restaurant close to Le Constellation and drove to the scene when he heard about the fire. "Everyone was burned, everyone was screaming, everyone was shouting," he told Reuters at a vigil held in Crans-Montana. "It was a horror movie. I've never seen anything like it in my life. And then I lost my best friend, who was in my arms. We tried to revive her." "I wouldn't wish that on anyone," he added. "That's why I tell everyone, now is the time for us to be together, for everyone to love each other, it's important.” You can hear his comments and see scenes from a vigil in the video below. This video can not be played Swiss official Stéphane Ganzer has been speaking to French broadcaster RTL. Earlier, reports quoting the Italian foreign ministry suggested that as many as 47 people were killed in the fire. Asked about this, Ganzer says he was "surprised" to hear the figure, saying it did not match up with what Swiss authorities were aware of, citing instead that around 40 people are known to have been killed. On injuries, Ganzer says between "80 and 100 people" are seriously injured and in need of urgent attention. The situation is evolving, Ganzer adds. He goes on to explain that people who have third-degree burns covering 15% of their bodies are at an increased risk of septicaemia and a subsequent heightened risk of death in the coming hours and days. Poland's Prime Minister Donald Tusk has shared his condolences with victims' families and loved ones. "Switzerland and the canton of Valais can count on Polish solidarity," he writes in a post on X. "We are ready, at Switzerland's request, to provide specialized medical care for the 14 injured in Polish hospitals." Around 40 people died in the blaze on New Year's Eve and 115 others are injured. Victims have not yet been identified but, as we've been reporting, several French and Italian citizens are among the missing. Nick JohnsonReporting from Crans-Montana The police have loosened the cordon for the first time since the fire. It means we’ve been able to get a bit closer to Le Constellation bar and see the scale of the police operation. White tents surround the entrances and exits and I can see bright police lights on inside. Daily life is trying to continue, however. Skiers clomp past with their boots and boards and cafes and shops are opening their doors. A bizarre paradox amid such heartbreak. We can now bring you a video which appears to show the first moments of the fire. The ceiling is alight - music can be heard playing in the background and some people are filming the fire on their phones. One man tries to extinguish the flames with a cloth as others look on. This video can not be played Footage shows person trying to put out flames during deadly Swiss bar fire Sarah RainsfordReporting from Crans-Montana Italian foreign minister Antonio Tajani will be in Crans-Montana today to visit the families of Italian citizens involved in the fire and to convey his government's solidarity. The number of Italians involved in the Crans-Montana disaster currently stands at 19, the Italian foreign ministry: The Italian ambassador to Switzerland, Gian Lorenzo Cornado, says the Swiss authorities are expected to provide an update on the situation after Tajani arrives. Several media outlets have named teenage Italian golfer Emanuele Galeppini as the first identified victim of the fire following a statement from the Italian Golf Federation. A spokesperson for the Italian foreign ministry tells the BBC it is not confirming this. In a tribute, the Italian Golf Federation calls Emanuele a "young athlete who carried with him passion and authentic values". But the statement does not mention the fire in Switzerland. Local Italian media had previously reported Emanuele's father had said his son was at the bar on the night of the fire, and that the family last had contact with him at midnight. We do not yet know the identities or nationalities of the victims, with local officials warning the identification process could take days or even weeks. But several French and Italian citizens are among the missing. A spokesperson for the UK Foreign Office says: “Our thoughts are with all those injured and killed in the terrible tragedy in Crans-Montana, and we pay tribute to the Swiss emergency services who are leading the response. "We will continue to monitor the situation, and our consular staff stand ready to support any British nationals who may be affected.” More than 24 hours after a devastating fire broke out at a New Year's party in the Swiss ski resort of Crans-Montana, here's what know, and don't know, so far: What we know What we don't know Imogen FoulkesReporting from Geneva Following the fire in Crans-Montana, the hospitals in the region remain under pressure. Mathias Reynard, the president of Canton Valais, told Swiss radio this morning that many staff had come in on their day off to help out, and that discussions were under way to bring in additional burns specialists from France. Meanwhile, the agonising wait for those missing continues. A spokesman for Canton Valais Police says the process of identification could take several days. The authorities are in constant contact with the families, he adds, and care teams were present to offer psychological support. Bruno Huggler, the head of tourism for Crans-Montana, says “the shock is still very deep today” in the Alpine resort town. He tells BBC Breakfast there are “two worlds” in the area as people mourn but holidays continue. Officials are trying to find the best way to have a "respectful atmosphere" for friends and relatives of the victims, with professionals on hand for them, as well as allowing other guests to enjoy the activities the area has to offer, he adds. Huggler explains that many different nationalities visit Crans-Montana, especially during the end-of-year period. More than 60% of visitors come from Switzerland while people often come from France and Britain, he adds, as well as nations such as Belgium, the Netherlands and Germany. Nick JohnsonReporting from Crans-Montana I’ve just spoken to a woman who lives locally and came to the scene for the first time since New Year’s Eve. She told me she’d just heard that both her friends who were at Le Constellation had died in hospital, after suffering the effects of breathing in smoke. They were both 20. She spoke of her guilt that she’s fine, while her friends’ family are suffering such heartbreak. It's now dawn in Crans-Montana. Firefighters and police remain at the scene, where the investigation is ongoing. See the latest pictures below. Axel Clavier said he was in the burning bar and had to break a window to escape This post contains details some readers may find upsetting. We've heard from a number of eyewitnesses and people who were in the bar at the time of the fire. "People were running in all directions, screaming and crying," eyewitness Daniella, from Milan, said. "A young man came up to me and said he'd seen hell - things he would never forget." One 18-year-old, who did not want to give his name, said he entered the bar during the fire to search for his little brother. "I saw people burning... I found people burning from head to foot, no clothes anymore," he said. Axel Clavier said he was trapped in the burning building and had to break a window to escape. "We couldn’t see because of the smoke," he told AFP, "half of my clothes were gone, it was crazy." He said before the fire started there were waitresses in the bar "with champagne bottles with flares too close to the ceiling", and that the "fire took hold suddenly". Two French women who were inside the bar when the fire also said they believe it began when a waitress put "birthday candles" on top of some champagne bottles. Emma and Albane, told French media outlet BFMTV “the entire ceiling was ablaze” within seconds as the flames “started to rise very quickly”. For context: Authorities have not yet said what they believe caused the fire. As we reported in our last post, a memorial of flowers, candles and messages remains at the scene this morning. Last night mourners gathered for a vigil in tribute to the victims - you can see images of the gathering below. Nick JohnsonReporting from Crans-Montana The scene outside Le Constellation this morning is one of two halves. Beyond the police tape are red and white forensics tents with officers appearing to go in and out of the area around the bar. The investigation active and visible. On the other side of the cordon, a quieter, reflective atmosphere. Dozens of candles flicker, lit at a vigil last night. And a large stage has been set up, atop which lie hundreds of bunches of flowers alongside messages of love and hope. While this is a very international resort, it does still feel like a close knit community. Locals I’ve spoken to in the short time I’ve been here all say they know someone who knows someone who was inside the bar that night. Investigators are continuing to examine what may have caused the fire but, as we have reported, many of the witnesses have described the speed at which it spread. The president of the UK Association of Fire Investigators, Richard Hagger, has told the BBC about the effect believed to have made the blaze so deadly. Speaking to The World Tonight, Hagger said: "A flashover basically is a rapid development of fire within a compartment. You'll start with a fire, the flames and the thermal radiation will go to the ceiling level and mushroom out across. "That thermal radiation then travels downwards on to other fuel packages, such as furniture, tables, raises the temperature to the point when they thermally decompose and produce flammable gas. "And then that gas ignites, but it ignites at a fairly rapid rate. So the room, in effect, becomes a full room on fire within a matter of seconds." Silvia CosteloeReporting from Crans-Montana This post contains details some readers may find upsetting. "I thought my little brother was inside so I came and tried to break the window to help people to exit, and after that I went in." The 18-year-old man, who did not want to give his name, spoke to the BBC after the huge fire, which turned what was an evening of celebration to ring in the new year into a nightmare. As others tried to escape, he went in, looking for his brother. Once inside, he described a scene of horror. "I saw people burning... I found people burning from head to foot, no clothes anymore," he said. "I went in this bar every day this week - the day I didn't go, it burned," he said. His brother was unharmed. Here's more from eyewitnesses who managed to escape the inferno.
