'Furnace Friday,' 'Stultifying Saturday,' call these days what you will - but Thursday's start to an epic heatwave saw several of Portugal's cities among the hottest in the world.
Data from the IPMA weather service showed ten of the 18 district capitals in Portugal hitting 40ºC or more - Riyadh, 42ºC, and Kuwait at 43ºC were topped by Santarém at 45ºC and Évora at 44ºC.
