The prosecutor general of the Valais canton, Beatrice Pilloud, confirmed this at a Friday news conference. The fire broke out in the basement. Many victims, including teenagers, were found there.

119 people were injured. Six remain unidentified. Survivors are being treated in hospitals across Switzerland, France, and Italy. Families are desperately seeking information.

The fire occurred in the Valais canton, a popular ski destination in Switzerland. The bar, Le Constellation, was a well-known establishment.
