Five suspects have appeared in court in France charged with terror offences in relation to the Nice truck attack.
The four men and one woman, aged between 22 and 40, are accused of helping driver Mohamed Lahouaiej-Bouhlel prepare the terror attack.
One of the suspects returned to the scene of the attack the following day to film the aftermath, French prosecutor Francois Molins said.
Lahouaiej-Bouhle killed 84 people when he drove into a crowd on Bastille Day.
He received logistical support for the attack from the five suspects, Mr Molins said, and had planned the attack for several months.
Three of the suspects, identified as Franco-Tunisians Ramzi A and Mohamed Oualid G, and a Tunisian named Chokri C, were charged as accomplices in "murder by a group with terror links".
An Albanian man named as Artan and a women who is a French-Albanian dual national, identified as Enkeldja, are suspected of providing Lahouaiej-Bouhlel with a pistol and were charged with "breaking the law on weapons in relation to a terrorist group".
All five will be held in custody, Mr Molins said.
