Authorities say at least 42 people died in a bus crash in southwestern France Friday.
Most of the passengers died instantly, according to officials.
Most of the victims were reportedly elderly people on a day trip with a social club.
French president François Hollande has called for a full investigation into the crash, calling it an "immense tragedy."
This is being called the worst traffic accident in France since a bus crash in 1982 left 53 people dead, mostly children.
