At least 46 people have been injured by an explosion at a foundry in northern France, during a demonstration for members of the public, officials say.
The blast happened at around noon at a bell-making foundry in Villedieu-les-Poeles, a town in the region.
Most of those hurt suffered minor burns or smoke inhalation and were treated on site, but one person had to be admitted to hospital, fire-fighters said.
The accident was probably caused by the explosion of a dust cloud, they added.
The blast produced a large cloud of smoke and showered the group of 50 tourists with molten bronze, police told the AFP news agency.
The Cornille-Harvard foundry in Villedieu-les-Poeles has been making bells since the Middle Ages and now exports them around the world.
