At least 60 people are reported to have been killed after a truck ploughed into a crowd in an apparent attack in the French city of Nice.
A further 100 people have been injured, according to French television station BFM TV.
The driver is reported to have picked up speed to slam the lorry into revellers celebrating Bastille Day on the city’s famous Promenade des Anglais.
One witness said he drove for at least 2-3 miles, mowing people down along the way.
He then emerged from the vehicle and started shooting, another witness told news agency AP.
“There was carnage on the road,” he said. “Bodies everywhere.”
