Mohamed Bouhlel killed 84 people after driving a 19-ton truck into a crowd which had been watching a fireworks display on the seafront during Bastille Day celebrations.
According to prosecutor Francois Molins, a search of Bouhlel's phone revealed searches and photos that indicated he had been plotting an attack since 2015.
"The investigation under way since the night of July 14 has progressed and not only confirmed the murderous premeditated nature of Mohamed Lahouaiej Bouhlel's act but also established that he benefited from support and complicity," Mr Molins said.

In fact, the delegates present were believed to be so enraged, that The Hill reported that Cruz's wife and father had to be escorted out of the building for their own safety.
