Swiss authorities hold their latest press conference following the deadly New Year's Eve fire at Le Constellation bar at the ski resort in Crans-Montana on Friday, January 2.

Authorities confirmed 'around 40' dead and a hundred more injured, many 'very seriously'. They have previously refused to comment on reports of 'champagne pyrotechnics' in the moments before the blaze - and potential safety concerns raised by the media about the bar's emergency exits and narrow staircase.
