Several people are said to have died after an explosion ripped through a bar in a popular Swiss ski resort.
The blast happened at 1.30am local time just as revellers were ringing in the New Year at the Le Constellation bar.
Swiss outlet Blick reports the blaze may have begun when fireworks were let off inside during a concert.
More than 100 people are thought to have been inside the bar at the time of the explosion, according to police. The venue had a capacity of 400 people.
