In Switzerland, a search is on for six people who went missing on Saturday during a ski tour that departed from the Alpine town of Zermatt. Police said, five skiers belonged to one family from the Valais canton, while the sixth person is from the canton of Fribourg. They said, these skiers went missing around Tête Blanche mountain on Zermatt-Arolla path, near Matterhorn mountain that straddles the border between Switzerland and Italy. Police said, the storm raging in the south of the Alps and the risk of avalanches has prevented helicopters and rescuers from approaching the area.
