British skiers heading to the Alps are being warned by French authorities that off-piste skiing this season is the most dangerous in years.

The season has seen unstable conditions, with 24 people killed so far in avalanches in France and Switzerland, including four this week.

The BBC's Christian Fraser has been to Montgenèvre on the Franco-Italian border to join search teams in training.
