Several people are feared dead and multiple others were injured after a powerful explosion struck a popular bar in the luxury Alpine ski resort of Crans-Montana in southwestern Switzerland early Thursday, according to local police. Authorities said the blast occurred during New Year celebrations, when the venue was crowded with revellers welcoming the start of the year.

Police in Wallis canton confirmed that the explosion took place at approximately 1:30 a.m. local time at Le Constellation, a well-known bar frequented by tourists and seasonal visitors. A spokesperson for the cantonal police said the cause of the explosion was not immediately known and that an investigation was underway to determine what triggered the incident.

Emergency services were rapidly deployed to the scene following reports of the blast. Firefighters, paramedics, and police worked through the night amid challenging conditions to control the fire and assist victims. Images circulating in local media showed the building engulfed in flames, with heavy smoke rising into the night sky as rescue teams operated nearby.

Officials said several people sustained injuries of varying severity, while multiple fatalities were feared, though an exact death toll had not been confirmed in the early hours. Authorities cautioned that the situation was still evolving and that identification of victims and notification of families would take time.

Crans-Montana is one of Switzerland’s most prominent ski destinations, attracting international tourists throughout the winter season. The incident has sent shockwaves through the resort community and raised concerns about safety during large holiday gatherings. Police have secured the area around the bar and urged the public to avoid the site while forensic teams continue their work.

Further updates are expected as investigators gather evidence and question witnesses to establish the circumstances surrounding the explosion.
