"Zurich University Hospital was seen on Thursday, as patients were airlifted following a deadly bar fire at a Swiss ski resort in Crans-Montana. According to media reports, local hospitals were 'full', with some injured people sent to those further afield. The latest information from the Swiss authorities suggested the 'majority' of the 100 reported hurt were 'seriously injured' - while numbers of dead varied from 'several' to 'several dozen' and 'tens' during the media briefing. The Italian foreign ministry said information from Swiss police suggested around 40 killed. The cause of the blaze also remained a mystery - with Swiss officials describing it as a 'fire, not an attack'. They did rule out an 'explosive device' following reports of a blast, but only after telling reporters there wasn't an explosion, then admitting there was a 'small' one, but which they said was due to the fire taking hold. They refused to be drawn on whether pyrotechnics were at play - after online videos showed sparklers served in drinks at the bar previously - and said there was 'no information' about whether the bar complied with safety standards. They did admit that it was 'likely' that victims were of 'different nationalities'. After two French nationals were confirmed hurt, Emmanuel Macron posted on social media: "Deep emotion following the fire in Crans-Montana. My thoughts go to the bereaved families and the injured. To Switzerland, to its people and to its authorities, I convey the full solidarity of France and our fraternal support.""
