Two people have been killed and several injured in a knife attack near a church in the French city of Nice.
The assailant was arrested after the Thursday morning attack and taken to a nearby hospital after being injured during his arrest, a police official said.
He was believed to be acting alone, the official said.
The lower house of parliament suspended a debate on new virus confinement measures and held a moment of silence for the victims.
The reason for the attack is unclear.
It comes as France is under high alert for terrorist attacks.
