More than 70 people have been killed and hundreds have been injured in Nice, France, after an unidentified driver drove a truck through a crowd of people celebrating Bastille Day.
The driver was reportedly shot and killed by police after driving through the crowd at up to 30 mph for more than a mile.
Within the truck, described as a large white lorry, police reportedly found weapons and grenades.
While the motivation for the attack is not yet clear, it appears to be deliberate.
French president Francois Hollander has labelled the Bastille Day attack an act of terror.
Casualties have reached 80 dead with another 18 critically wounded.
