A 15-year-old girl of Greek descent who holds dual Greek and Swiss citizenship and lives permanently in Switzerland is among those reported missing after a deadly fire at a bar in the Swiss resort town of Crans-Montana.

The blaze erupted in the early hours of New Year’s Day at Le Constellation, a popular venue where revelers were celebrating the arrival of 2026. Nearly 40 people were killed and more than 115 injured, according to authorities. Many of the victims were young people, and several were visiting from other countries.

According to the latest information, the missing teenager is Alice Kallergis. Reports say she was at the bar with friends when it was engulfed in flames. There has been no official update on her fate so far, and three friends who were with her at the time are also reported missing.

Her brother has issued a public appeal on social media for information, saying the family has had no news since the fire broke out.

“My 15-year-old sister, Aliki Kallergi, is missing. We have no information since the fire at a bar in Crans-Montana,” he wrote. “If you have seen her or know whether she has been taken to a medical facility, please contact me. Please share this message as widely as possible. She was with three friends, who are also missing.”

Authorities continue efforts to identify victims and account for those still unaccounted for as investigations into the fire remain ongoing.

The cause of the fire remains under investigation, with two main theories emerging: either a firework placed inside a champagne bottle ignited the ceiling, or a bartender accidentally set fire while lifting a waitress holding a candle in a champagne bottle. The blaze spread within seconds, fueled by the bar’s largely wooden interior, trapping patrons in a narrow underground area.

International Impact

Italy reported that approximately 15 Italian visitors were injured, some with severe burns covering 30–40% of their bodies, and several remain missing. France confirmed six injured citizens and eight missing, with some already receiving treatment in French hospitals.

Eyewitness Accounts

Survivors described chaotic scenes as the fire spread. Many were trapped in the narrow staircase leading out of the underground bar, while others attempted to rescue those inside. Videos circulating online show panicked patrons fleeing and flames quickly engulfing the space. Greek visitor Kelly Diolatzis described the crowd as “extreme” with thousands of young people from various countries, and recounted fireworks being used dangerously inside the bar during the New Year celebrations.

Authorities Respond

Swiss authorities continue DNA collection and victim identification, a process expected to take weeks due to the extensive damage and lack of a guest list. The federal government has declared a five-day period of mourning. Swiss President Guy Parmelin called the incident “one of the most traumatic events in Switzerland’s history,” honoring the young lives lost.

The European Commission confirmed it is coordinating with Swiss authorities to provide medical assistance. French President Emmanuel Macron expressed solidarity, offering treatment for victims in French hospitals and praising the efforts of rescue teams.

Le Constellation, opened in 2015, had a capacity of up to 300 inside and 40 on a heated terrace. Both owners, a couple of French origin, are reported to be alive.
