Nice attack: Tunisian man behind truck attack was radicalised very quickly

Authorities have yet to produce evidence that Mohamed Lahouaiej Bouhlel, 31, shot dead by police, had links to Islamic State, (IS) which claimed the attack, but Mr Valls said there was no doubt on the assailant’s motives.
“The investigation will establish the facts, but we know now that the killer was radicalised very quickly,” he said in an interview with Le Journal du Dimanche. “The claim on Saturday morning by Islamic State and the fast radicalisation of the killer confirms the Islamist nature of this attack.”
