A devastating fire in the Swiss Alps claimed dozens of lives and left at least 100 others injured during New Year’s festivities, according to police.

The blaze occurred in the area of Crans-Montana, Switzerland, police confirmed.

“The fire started around 1:30 a.m. this morning at a bar called ‘Le Constellation,'” commented police spokesperson Gaëtan Lathion. “There were over a hundred people in the building, and we are seeing many who are injured or dead.”

Later, Swiss police reported that “several tens of people” are presumed dead, with around 100 individuals injured—many of them seriously. Authorities could not immediately provide more precise casualty figures.

Police stated that investigators were working to determine the cause of the fire.

The Valais Canton attorney general said it was too early to establish the fire’s cause, but authorities have ruled out terrorism.

“We’re just at the beginning of our investigation, but this is an internationally renowned ski resort with lots of tourists,” Lathion noted.

The number of injured people overwhelmed local medical resources, as the intensive care unit and operating theater at the regional hospital reached full capacity. Victims were transferred to other nearby hospitals, officials said.

A reception center and helpline have been established for families of victims, Lathion said.

Authorities urged local residents and visitors to exercise caution in the coming days to avoid accidents that could further strain emergency medical services during the busy ski season.

The community lies in the heart of the Swiss Alps, roughly 25 miles north of the Matterhorn.
