Authorities say five French Foreign Legionnaires on a wilderness ski training exercise in the French Alps have been killed in an avalanche near the Italian border.

At least six others taking part in Monday's off-piste (course/trail) training were reported injured near the resort of Valfrejus.

Monday's avalanche comes just days after two French teenagers and a Ukrainian tourist were killed in a similar incident in the same region.

A French instructor who took two of the victims onto a closed skiing piste and survived the January 13 avalanche has been charged with involuntary manslaughter. The third victim was not part of the group.
