The shooting took place on Friday morning, when an individual fired shots from a vehicle at several people, according to the Mayor of Trappes, Ali Rabeh. French Interior Minister Laurent Nunez said the attacker used an automatic weapon.
French Prime Minister Sebastien Lecornu described the events as "very serious" and confirmed that the suspect had been taken into custody. President Emmanuel Macron expressed his "deep emotion" and solidarity with the victims, stating that "the nation stands by their side."
The National Anti-Terrorist Prosecutor's Office is investigating the incident on charges of "murder in connection with a terrorist enterprise", as well as possession of a Category A weapon and conspiracy with a terrorist group. Reports in French media suggest the number of injured may be higher than the official tally, and that a 12-year-old child may be among the wounded.
The motive behind the attack remains under investigation, and authorities have not yet released details about the suspect or any potential organisational links.
