A Truck has struck a crowd during Bastille Day celebrations in the southern French city of Nice, with reports of many dead.

The incident took place on the famous Promenade des Anglais during a firework display, media reports say. Further development is that seven occupants of the Truck, first started shooting guns into the crowd at the same time driving into the crowd. Police shot the truck and killed the driver from moving further. 
One image on Twitter showed about a dozen people lying on the street, some being tended to. The local prefecture has urged people in the area to remain indoors, calling the incident “an attack”. Nice Mayor Christian Estrosi said that “a lorry driver appears to have killed dozens of people”.

One witness, an American who was about 15 feet from the truck, said the driver pointed his tractor trailer into the crowd, mowing bodies over. BFM-TV, reported police exchanged gunfire with people in the truck.

Here are the latest developments in the tragedy:

Maryam Violet, a witness, said she was walking along the beach and saw “a ton of people on the ground and on the sidewalk.” “You could see someone with a bike or a wheelchair and someone with a bag full of flowers, innocent and normal people on the beach.”

The driver mounted the pavement at 40mph and steered directly at large groups of people watching the fireworks 

Heavily armed soldiers occupied the centre of the town to restore control after the attack which claimed at least 50 lives 

Sebastien Humbert, the prefect of the Alpes-Maritimes region, told France’s BFM TV that “perhaps about 30 people” were dead and 100 injured. He said the lorry driver had been shot dead. The mayor and police urged residents to stay indoors. Some reports spoke of shots being exchanged between police and the occupants of the lorry but these have not been confirmed.

Social media video showed people running through the streets in panic following the incident.
A journalist with the Nice Matin newspaper reported from the scene that there was “a lot of blood and without doubt many injured”.

An Agence France-Presse reporter said the incident took place as the firework display was ending, adding: “We saw people hit and bits of debris flying around.”
Another image on Twitter showed a white lorry stopped in the middle of the promenade with damage to its front, and four police officers observing it while taking cover behind a palm tree.

One eyewitness told BFM TV: “Everyone was calling run, run, run there’s an attack run, run, run. We heard some shots. We thought they were fireworks because it’s the 14th of July.
“There was great panic. We were running too because we didn’t want to stick around and we went into a hotel to get to safety. “

Another witness, Roy Calley told the BBC that there were “thousands of people on the promenade” when the incident happened.
