One person is dead and 13 have been injured as the largest wildfire France has seen in decades continues to burn across the nation's southern Aude region.

Prime Minister François Bayrou described the nearly 40,000-acre fire, which has killed one person, as a “catastrophe on an unprecedented scale.”

France's largest wildfire for 75 years, which has burned through an area larger than Paris, has slowed overnight but is not yet under control, officials have said. More than 2,000 firefighters and 500 firefighting vehicles continue to be deployed to the Aude region, alongside gendarmerie and army personnel, officials said on Thursday.
