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.

PARIS (Reuters) -A wildfire that had reached the northwestern outskirts of France's second city of Marseille lost intensity overnight on Wednesday, but the airport was expected to close as firefighters continued to battle the flames. Residents who had been told to stay in their homes for their own safety were once again allowed out.

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 or barricade themselves indoors as smoke choked the Mediterranean air.
