French President Francois Hollande has said that around 50 people are in critical condition, still "between life and death" after an attack in the southern city of Nice.
Hollande travelled to Nice after holding a crisis meeting in Paris to discuss security measures.
During Bastille Day celebrations, a man drove a delivery truck down the beachfront promenade in the French Riviera city killing 84 people and injuring many more. The truck drove at least 2 kilometres along the crowded street.
Hollande said the attack was terrorist in nature.
