Swiss authorities say they have rescued everyone who was buried in a "severe" avalanche that occurred on the Eiger mountain on Saturday, and that there are no missing people.

The avalanche at the Swiss Alps took place shortly after midday on Saturday, prompting police to launch a large-scale rescue operation.

"All people have been flown out," Bern Cantonal police said on Saturday evening, without specifying the number. Authorities had deployed several teams.

The Eiger is a 3,967m (13,000 ft) peak near the tourist resorts of Grindelwald, Lauterbrunnen, and Wengen.
