At least 73 people are reported to have been killed and dozens injured after a truck ploughed into a crowd in an apparent attack in the French city of Nice.
Local officials are reporting that the driver has been killed, while local newspaper Le Parisien is saying a possible accomplice has fled the scene.
Several weapons, guns and grenades were found inside the vehicle, a local source told local newspaper Le Figaro.
The attack happened as spectators gathered to watch a Bastille Day fireworks display on city’s landmark promenade, which runs some four miles along the waterfront. Authorities in Nice are urging local residents to stay in their homes.
The Gendarmerie Nationale tweeted: “Emergency operation in progress. Keep calm and avoid downtown area. Follow the official accounts to be informed.”
