Deadly fires are raging through Spain and Portugal as the worst wildfire season on record continues across the continent.

Villages have been evacuated, farmers drafted in to fight the flames, and huge areas of land have been destroyed, four times the average for this time of year, official figures show.

More than 1million hectares have burned so far, smashing the previous record of 988,544 hectares set in 2017, with more dangerous fire weather still to come.

Homes have been reduced to ashes, forests turned black, and thick smoke has blanketed cities for miles.

The blazes have pumped out around 37million tonnes of carbon dioxide – roughly the same as the annual emissions of Portugal or Sweden – while PM2.5, particles, which can penetrate deep into the lungs, have hit record levels.
