Full coverage: Bastille Day Attack In Nice, France

At least 84 people have been killed and about 100 others injured after a truck ploughed through a crowd celebrating Bastille Day in the southern French city of Nice.

Among those killed were 15 children. Eighteen people remain in a serious condition. The attack happened Thursday night 11p.m. local time, when a truck driver drove along the famed Promenade des Anglais seafront at high speed for more than two kilometers and opened fire on the crowd. Police shot and killed the driver of the truck.

Weapons and grenades were found inside the truck. Police also found identity papers belonging to a 31-year-old French-Tunisian inside the truck.

While the attack has not been claimed by any group, prosecutors said the probe would be handled by anti-terrorist investigators. Officials are also investigating if the driver acted alone.
