Mayor Christian Estrosi said on Twitter the knife attack had happened in or near the city’s Notre Dame church and that police had detained the attacker. Police said three people were confirmed to have died in the attack and several were injured. A police source said a woman was decapitated. French politician Marine Le Pen also spoke of a decapitation having occurred in the attack.
The French anti-terrorist prosecutor’s department said it had been asked to investigate the attack.
Reuters journalists at the scene said police armed with automatic weapons had put up a security cordon around the church, which is on Nice’s Jean Medecin avenue, the city’s main shopping thoroughfare.
Ambulances and fire service vehicles were also at the scene.
