Nice truck attacker Mohamed Lahouaiej-Bouhlel received logistical support for his Bastille Day attack from five suspects who are now in custody, French prosecutor Francois Molins has said. Mr Molins told a news conference the crime had been planned for months. He said one of the suspects had filmed the scene of the attack the day after. All five are facing preliminary terrorism charges for their alleged roles in helping Lahouaiej-Bouhlel, a Tunisian living in Nice.
