Spain is deploying 500 more soldiers to help battle wildfires that have ravaged parched woodlands during a prolonged heatwave, Prime Minister Pedro Sánchez said.

Firefighters in Spain, Portugal and Greece battled ongoing wildfires Friday, an important religious holiday in all three countries, as persistent hot, dry conditions challenged efforts to contain the blazes.

Hazy sunshine has replaced last week's fierce heat in parts of the UK, and it's down to how smoke particles break up rays of light, but along with the lower temperatures, there could be some memorable sunsets and sunrises.
