Black smoke and the smell of burned waffles filled the city of Brussels on Thursday after a factory making the Belgian dish caught fire.
While no one was injured in the fire, it destroyed most of the factory and the plume covered railways, disrupting trains to London, Paris and elsewhere.
Local media quoted officials saying the fire was caused by a malfunction in an oven cooling system.
The smoke spread some six kilometers from the factory, prompting local police to warn people to stay indoors and shut windows so as not to inhale the smoke.
