Rescuers have been digging through the snow looking for survivors
One person has died and three people are injured after an unexpected avalanche on a marked ski slope at a popular resort in the Swiss Alps.
Hundreds of rescuers searched through the night, but called off the search Wednesday morning after no-one was reported missing.
A 34-year-old French national died in hospital, Swiss police said.
The avalanche was unusual in that it fell on a popular, marked slope when the avalanche risk was deemed low.
Most people caught in avalanches are skiing "off-piste", away from the slopes maintained by ski resorts and used by the majority of tourists.
Such slopes are usually very safe, as the snow around them is carefully monitored and managed to avoid risks.
The avalanche risk in the region was set at only two out of five on Tuesday.
It happened in Crans-Montana at about 14:20 local time (13:20 GMT), when the avalanche engulfed 400m (1300ft) of piste marked out for skiers, local police commander Christian Varone said.
The dead person had been working in Crans Montana's ski patrol service, police said.
