This was reported by the BFMTV TV channel.

It is noted that the alleged attacker was quickly detained.

As the Mayor of Nice, Christian Estrosi, noted on his Twitter page, all the circumstances of the incident indicate that the attack is a terrorist act.

“I confirm that everything points to a terrorist attack,” he wrote.

Je suis sur place avec la @ PoliceNat06 et la @pmdenice qui a interpellé l'auteur de l'attaque.

Je confirme que tout laisse supposer à un attentat terroriste au sein de la basilique Notre-Dame de # Nice06.
