Europe's continuing heat wave on Wednesday helped fuel a deadly wildfire in Spain while the European Union presented plans to reduce greenhouse gas emissions under scorching temperatures.

A heatwave continues to grip large parts of Europe, with authorities in many countries issuing health warnings amid searing temperatures.Southern Spain is the worst-affected region, with temperatures in the mid-40s Celsius recorded in Seville and neighbouring areas.
