French Prime Minister Jean Castex told reporters that “violence” has taken place but “we do not yet have a clear composition.” Castex also said the “Crisis Center” would be activated.
The French Interior Ministry has said that serious security incidents are taking place near the Jean-Macé quarter of Lyon and security has been put in place.
France raised its national terror alert alert on Thursday to the highest “emergency” level, with up to 4,000 troops deployed to increase security at schools, churches and other places of worship.
Castex was in the village of Saint-Etienne-du-Rouvray in northern France, where he traveled on Saturday to inspect the security measures in place in the wake of the Nice attacks.
