A baby has died and several people have been seriously injured after a bus of Romanian tourists crashed near Vidauban.
The fire service says that of the 40 passengers aboard, up to eight people are in a critical condition.
The bus was heading towards Nice when it appeared to skid. It ploughed through the central reservation and overturned, ending up on the other side of the highway. Authorities report that the accident may have been caused by a burst tyre.
Emergency services transported the victims to hospitals in Marseille, Nice and Toulon.
