Italy's government has filed to be a civil party in the criminal proceedings regarding a fire at a Swiss bar that killed 41 people, including six Italians. The fire, caused by sparklers igniting sound insulation, occurred during New Year's celebrations. The bar owners face charges of negligence and arson. Italian Prime Minister Giorgia Meloni has promised justice for the victims and criticized a Swiss hospital for billing families of victims. Italy is monitoring the investigation and demanding compensation from those responsible.
