Investigators were working to determine the cause of the fire, police said.

“We’re just at the beginning of our investigation, but this is an internationally renown ski resort with lots of tourists,” Lathion said.

A reception center and helpline have been established for impacted families, Lathion said.

A news conference was scheduled by police for 10 a.m. The community is in the heart of the Swiss Alps, about 25 miles north of the Matterhorn.
