Nice - French President Francois Hollande presided at a ceremony on Saturday paying homage to the 86 people killed when an Islamic extremist rammed his truck into crowds watching holiday fireworks in Nice.The ceremony took place atop a hill overlooking the Promenade des Anglais, the scene of the slaughter, in the presence of families, injured people, religious representatives, France's main political leaders and Nice local authorities.The names of the 86 victims were read and 86 white roses placed on the centre of the ceremony square.Cindy Pellegrini, who lost six family members in the attack, recalled France's ideal of "liberty, equality, fraternity."Our sadness is undefinable," she said. "How to live with physical wounds? How to live with moral wounds?"Still reeling"It's national unity that has been hit on July 14. That's the monstrous target of the terrorists," Hollande said. "Hitting some to scare the others, unleashing violence to create division, instilling fear to fuel distrust and stigmatisation."This evil project will fail. Unity, liberty, humanity, in the end, will prevail," he said.The attack killed people from 19 nationalities - including 15 children and teenagers. The youngest victim was two and the oldest 92, the French president recalled.The southern French city is still reeling from the July 14 attack.Flowers, teddy bears and flags of different nations were floating on a makeshift memorial near the Promenade des Anglais.
