rs in the streets since the November attacks, and much of the country was under intense security during the month-long European football championships, which ended July 10 without incident.
The regional president, Christian Estrosi, told BFM TV that "the driver fired on the crowd, according to the police who killed him."
Video footage showed men and women — one or two pushing strollers — racing to get away from the scene. Photos showed a truck with around 20 bullet holes.
Writing online, Nice Matin journalist Damien Allemand, who was at the waterside, said the fireworks display had finished and the crowd had got up to leave when they heard a noise and cries.
"A fraction of a second later, an enormous white truck came along at a crazy speed, turning the wheel to mow down the maximum number of people," he said. "I saw bodies flying like bowling pins along its route. Heard noises, cries that I will never forget."
On video footage of the attack, one person could be heard yelling, "Help my mother, please!" A pink girl's bicycle was overturned by the side of the road.
Hollande announced a series of measures to bolster security. Besides continuing the state of emergency and the Sentinel operation with 10,000 soldiers on patrol, he said he was calling up "operational reserves," those who have served in the past and will be brought in to help police, particularly at French borders.
He reiterated that France is also bolstering its presence in Iraq and Syria, where he said earlier that military advisers would be on the ground to help Iraqis take back the Islamic State stronghold of Mosul.
President Barack Obama condemned what he said "appears to be a horrific terrorist attack."
European Council president Donald Tusk said it was a "tragic paradox" that the victims of the attack in Nice were celebrating "liberty, equality and fraternity" — France's motto — on the country's national day.
