About 1,400 firefighters were deployed on Saturday in France‘s southern Aude region to prevent the country’s largest wildfire in decades from reigniting, as all residents were allowed to return to their homes.

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