PARIS, FRANCE - JULY 15: The French flag is at half mast after a Security and Defense Council, chaired by French President Francois Hollande at the Elysee Palace on July 15, 2016 in Paris, France. The Security Council was held after yesterday's attack by Mohamed Lahouaiej Bouhlel, a Tunisian-born Frenchman, after he drove a lorry through crowds gathered to watch a firework display during Bastille Day celebrations on the Promenade des Anglais in leaving 84 dead and many more injured in Nice.
