The spokeswoman of Lenval children's hospital in Nice, Stephanie Simpson, said the boy is Romanian and had been visiting Nice with his parents, who are missing. But, in a attack-in-nice/" target="_blank">statement to reporters, Interior Minister Bernard Cazeneuve hinted that Bouhlel may have had a last-minute adoption of a more extremist worldview.
Valls also warned that "terrorism will be part of our daily lives for a long time". "He wasn't very nice...."
Some 30,000 people had thronged the palm tree-lined Promenade des Anglais on Thursday night to watch a fireworks display, but only 50 municipal police officers and 62 national police officers were on duty, according to sources.
The woman's lawyer, Jean-Yves Garino, told BFM-TV that Bouhlel physically abused her and the rest of the family, and she eventually threw him out of the house.
"I never saw him at the mosque", said the caretaker of an apartment building as he sat in a restaurant next to the mosque.
It came after Bouhlel's uncle claimed his nephew was indoctrinated about two weeks ago by an Algerian member of the Islamic State group in Nice.
Bouhlel began the attack at about 10:45 p.m., driving the truck into people. But Cazeneuve said that high security had been assured in the region - including at the Cannes Film Festival and the Nice Carnival.
The Islamic State group claimed responsibility Saturday for the truck massacre in Nice, as France highlighted the "extreme difficulty" of preventing such attacks amid tough questions over security failures.
The bill to be debated in parliament on Tuesday night would also grant police and spy services greater powers to dig into suspects' computers and mobile phone communications.
He said police cars were unable to follow the truck onto the seaside walkway after it had "violently forced through the barriers" and onto the sidewalk.
France held a countrywide moment of silence Monday to remember the victims, but the national mourning was punctured by anger and political division.
Bouhlel's neighbours described the attacker as "very, very beautiful" with Mediterranean looks who wore so much perfume you could tell by the smell when he was in his rental apartment in the eastern district of Abbatoir.
French officials couldn't confirm Monday that attacker Bouhlel had been approached by an Algerian recruiter, saying that the investigation is ongoing.
Hollande was expected to meet Czech leaders on Wednesday.
NICE, France The Islamic State group claimed Saturday that the Tunisian man who barreled his truck into a crowd in the French resort city of Nice was a "soldier" of the group. According to the AP, there is no evidence ISIS was involved in planning or carrying out the July 14 attack. More than 200 people were injured, and at least 55 of them were in critical condition Friday.
The investigation showed Mohamed Lahouaiej Bouhlel had trawled the internet for information on a terror attack in the USA city of Orlando and on the killing of a police couple in a Paris suburb last month, Francois Molins said.
Seven people remain in custody following arrests during the weekend. Messages seeking further detail were not returned.
