Nine skiers were hit by an avalanche yesterday on the Piz Vilan mountain, of whom five died.
A 31-year-old Swiss man was also killed by the avalanche yesterday while he was skiing off-piste in the Bernese Oberland, and in the same area a 28-year-old Swiss snowboarder was engulfed by snow and died.
In another fatal accident, in Wildhaus near the Austrian border, a 26-year-old skiing off-piste provoked a snow slide that sent him over a cliff, police said.
Up to 1.2 metres (four feet) of snow has fallen in the region in recent days.
