Journalist Jon Bryant has told talkRADIO the whole city of Nice is "shell-shocked" following Thursday night's atroctites.
The attack, which saw a truck mow people down as they celebrated Bastille Day, killed 84, while around 50 are still in hospital.
Bryant has lived in Nice for five years, and describes the feeling there.
"It's a devastating scene even now, people don't really want to talk about it. Most people who live here will know someone who was affected," he told Yasmeen Khan.
"The whole city is absolutely shell-shocked, absolutely devastated, people can't really even speak, you just see people give them a hug and go home. It's a strange atmosphere because there are still loads of tourists here.
"It's a holiday resort, so there's loads of restaurants and bars, you've got rollerblading on the front, but there is an underbelly.
"There are parts you wouldn't really want to go after 8pm at night, and I think there are feelings of division a little bit."
