A blaze in southern France forced the closure of the Marseille airport, and weather agencies issued warnings for other parts of Europe where temperatures were expected to climb this week.

A 10-day heat wave that ended on July 2 pushed temperatures above 40C (104F) across parts of Western Europe. According to scientists from Imperial College London and the London School of Hygiene and Tropical Medicine, climate change intensified the heat by as much as 4C (39F) in 12 major cities, including Barcelona, Madrid, Milan, and London.

The heat wave in Europe helped fuel a wildfire in Spain that killed two farmers, taking hundreds of firefighters to bring it under control.

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 wildfire that had reached the northwestern outskirts of France's second city of Marseille lost intensity overnight on Wednesday, but the airport was closed as firefighters continued to battle the flames.
