Weather maps show large swathes of red - temperatures regarded as dangerous - across most of Southern Europe over the next few days.
Temperatures may this week peak at a fierce 45C in parts of Spain, Greece and Italy, and in the latter at least three people have already died due to the heat. The heatwave - dubbed "Cerberus" - will see temperatures 10-15C higher than average for the time of year across much of the continent.
And in Prague, Czech Republic, where temperatures barely exceed 24C in June, the mercury is expected to hit a sweltering 34C by the weekend. North Africa is also set to suffer from extreme heat, where temperatures are forecast to reach 50C.
