>> A terrorist attack on liberty, that's what French president François Hollande is calling Thursday's horrific crash in the city of Nice. At least 80 people are dead after a truck plowed through a crowd gathered to watch Bastille Day fireworks, the driver later shot dead by police. Hundreds of people have been rushed to hospitals.
Reuters Tom Bergin is on the scene.>> Yeah, I just met somebody who worked in the Children's Hospital, and they said that they had many children that had come in there, basically very severe operations that are going on at the moment on some of the children in the hospital.
>> Police say at least 18 people are in critical condition, meaning the death toll could still rise. Eyewitnesses described scenes of horror with lifeless bodies covering the pavement.>> The 14th of July here, it's a big day, it's the big night, beginning of the holiday season. The woman I saw was sitting in a cafe and just saw the truck whiz by, and really, it's slightly surreal, a scene that she describes, and that's how she felt about it.
People were just shocked that something like this has happened in their community.>> Investigators say weapons and grenades were discovered inside the truck. They're now working to identify the driver. According to local media, he may have been a young local originally from Tunisia. Experts say Nice has seen Islamist activity in the past, with some Muslim residence even travelling to fight in Syria.
France is still reeling from last November's Paris attack when Islamic state militants gunned down 130 people. That tragedy prompted President Hollande to call for a state of emergency, which has now been extended.
