At least 84 people have died and scores have been injured after a truck crashed into a crowd of people in the south of France.
A further 18 people are seriously injured and many others hurt.
The dead include a number of children.
Witnesses described how the driver of the articulated lorry sped along a promenade packed with spectators leaving a fireworks display marking France’s national holiday.
Francois Hollande, the country’s president, said the killings were a terrorist act and extended the state of emergency for a further three months.
