DEVELOPING: Dozens were killed Thursday after a large truck drove into a crowd of people who had gathered for a Bastille Day fireworks show in the southern French city of Nice, a regional official said.
Nice Mayor Christian Estrosi said on Twitter that there appeared to be "dozens" of fatalities, while the French TV channel BFM reported that at least 30 people had died. No casualty figures were immediately given by authorities.
The apparent attack happened at around 10:30 p.m. local time on the Promenade des Anglais, the city's main boulevard along the Mediterranean Sea.
The Nice-Matin newspaper quoted one of its reporters as saying the truck driver "mounted onto the Prom and he drove on everyone." The reporter added, "people are running, it's panic."
A photo taken by the reporter showed around a dozen people lying in the street, with some being tended to by emergency personnel.
Reports of shots being fired could not immediately be confirmed, and may have been confused with the sound of fireworks.
The paper posted an image of the truck on Twitter, captioning it, "The truck that drove into the crowd."
