An eyewitness of the deadly attack in Nice has said there was no security when the lorry began ploughing into crowds.
"There was no security and it took firefighters close to half an hour to arrive on the scene," the man told Euronews.
"The truck was there on the promenade and then they shot the driver. The truck mounted the kerb, accelerating into the crowd as it ran over everyone on its way."
French Prime Minister Manuel Valls faced boos and calls to resign as he laid a wreath for the 84 people killed in the lorry attack in Nice.
Hours later Mohamed Lahouaiej Bouhlel drove a 19-tonne lorry down the promenade killing 84 people and injuring 200 more.
France's prime minister stated on Sunday he believed the man behind the Nice lorry attack was radicalised "very quickly"
