A full investigation into the events surrounding the deaths of 84 people in Nice is underway. Details are continuing to emerge about the 31-year old Franco-Tunisian man whose papers were found in the lorry after the attack. 

The regional president in Nice, Christian Estrosi has called for the investigation to focus on any accomplices. 

"Attacks aren't prepared alone. Attacks are prepared with accomplices," Estrosi said. "There is a chain of complicity. I expect it to be unveiled, discovered and kept up to date."

Police have gathered information from some of the city's 1,200 security cameras and have been able to pinpoint the moment the attacker boarded the vehicle. It has been revealed that he entered the lorry near the hills of nice. The CCTV footage documents the man's entire journey.

It is thought the police will now look further back into the CCTV footage of the surrounding areas to paint a fuller picture of the attacker's movements in the hours prior to the horrific events of last night. 

Mr. Estrosi said more than 10 children were among the dead and he said France needed to think carefully about its next response to attacks, as previous responses were not enough to protect the people.
