A French prosecutor says Nice attacker Mohamed Lahouaiej-Bouhlel had been planning for months and had five accomplices, who have since been arrested.
Eighty-four people were killed and 303 injured during the attack when a 19-tonne cargo truck was deliberately driven into crowds celebrating Bastille Day on the Promenade des Anglais in Nice, France.
One of the suspects had allegedly filmed the scene of the attack the day after, prosecutor Francois Molins said, and all five suspects – four men and a woman – are now facing preliminary terrorism charges for their alleged roles.
According to the BBC they include an Albanian couple suspected of providing Lahouaiej-Bouhlel with a pistol and a 22-year-old man believed to have received text messages on the night of the attack, discussing the supply of weapons.
Searches made by Lahouaiej-Bouhlel on his phone show he may have been planning the attack since 2015.
