Major heat waves across southern Europe have pushed temperatures above 104 degrees Fahrenheit (40 degrees Celsius) in countries including Italy, Spain and Greece, as local authorities issued fresh warnings against the risk of wildfires.

Wildfires are frequent in Greece during its hot, dry summers. In 2018, a massive fire swept through the seaside town of Mati, east of Athens, trapping people in their homes and on roads as they tried to flee. More than 100 died, including some who drowned trying to swim away from the flames.
