A group of students were on the Promenade des Anglais at the time of the incident.
One of them, Anthony, said: “The fireworks ended, and we went back.
“At that time we saw the white truck. A six tonne truck. It was speeding at 60 km/h, 70km/h.
“I saw behind the wheel, the driver was deciding which way it was heading. The truck rolled on to the pavement.
“It happened two meters from us. I saw people lying on the ground, I saw a small child hit the earth.”
A reporter for the Nice Matin newspaper who was covering the celebrations added: “There are people in blood, probably full of wounded.”
Fabien Lallemand said he saw a “huge white truck traveling at breakneck speed” which clearly intended to “mow down the maximum number of people”.
He said: ”I saw bodies flying like bowling pins in its path. I heard noises, screams, that I will never forget. I was paralysed. I did not move.
“Around me, there was panic, people were running, screaming, crying. Then I realized. And I ran with them.”
