WATCH: Helicopters search for skier in Switzerland as five others found dead

Rescue teams searching for a missing skier in the Alps found an “ice cave” dug by a desperate family trying to avoid freezing to death.

The six cross-country skiers, five of them members of the same family from Valais canton, went missing near the 3,710 metre-high Tête Blanche mountain on Saturday on the Zermatt-Arolla path on the Swiss-Italian border.
