A fast-moving wildfire reached the outskirts of Marseille, France’s second-largest city, on Tuesday, leading its airport to be shut down, with residents told to stay indoors and shut all openings to be safe from the smoke.

A fast-moving wildfire in southern France is affecting travel just as the French summer vacation period begins.

Over 1,000 firefighters were sent to battle the blaze that started near Les Pennes-Mirabeau and quickly spread toward the city of Marseille.
