A teenager who attended a private Jewish school in Hertfordshire is missing after a devastating fire at Le Constellation bar in the Swiss resort of Crans-Montana. The incident occurred during New Year's celebrations, with the venue crowded with both locals and tourists. Initial investigations suggest the blaze was likely caused by sparklers on champagne bottles being carried too close to the ceiling. Swiss authorities have launched a thorough investigation into the materials used at the site, fire safety measures, and the bar's capacity at the time. Identification of the victims may take several days or weeks, as officials continue to account for those affected. The family of the missing teenager has asked for thoughts and prayers during this difficult time.
