A wildfire spurred by hot summer winds reached France's second-largest city Tuesday, grounding all flights to and from Marseille, injuring at least nine people and forcing many residents to evacuate their homes or barricade themselves indoors as smoke choked the Mediterranean air.

Flights to and from Marseille have been suspended and traffic at the city’s main train station was disrupted due to a wildfire near the southern French port city.

The prefecture urged people in the affected areas to stay indoors and off the roads. With the fire approaching Marseille, the prefecture also advised residents in the northern area of the city to remain inside with doors and windows closed to prevent toxic smoke from entering their homes.
