A fourth person died as wildfires blaze on in Spain and parts of Europe worsened by sweltering heat fueled by effects of climate change. Spain's weather agency, Aemet, warned the public on Monday to be "cautious" of the "very high or extreme fire danger" in most of Spain as it reported high 108 degree Fahrenheit temperates on Sunday in Cadiz in the southern tip of Spain only miles to the Strait of Gibraltar.

Thousands of firefighters worked overnight to contain dozens of deadly wildfires burning across Spain and Portugal as heat and gusty winds spread blazes through dry brush, forests and crops.

“Homes are still under threat so we have lockdowns in place and are carrying out evacuations,” Rueda said.
