Residents in southern Madrid have been warned to stay indoors as a toxic cloud from a nearby fire engulfs part of the city. Emergency services announced on social media early Saturday that a fire in an industrial building in the Fuenlabrada neighborhood was to blame. One man has been taken to a hospital to receive treatment for burns, they said. A nearby hotel and industrial building have also been evacuated. It was not immediately clear what chemicals were released as a result of the fire.
