PARIS (AP) — Authorities say fireworks in a French Riviera resort town appear to have prompted a panic that led to dozens of injuries as people scrambled to flee.

Residents are on edge around the country after a string of deadly attacks, including the Bastille Day truck rampage in Nice last month that killed 85 people after a fireworks show.

About 20 kilometers (12 miles) down the coast from Nice, loud sounds that apparently came from small-scale fireworks sent restaurant-goers fleeing in alarm Sunday.

The local administration reported Monday that about 40 people were injured in the melee.

Nice-Matin newspaper quoted witnesses who described confusion and fears of a new attack.

France has been under a state of emergency since Islamic extremist attacks in November killed 130 people.
