Hundreds of firefighters battled wildfires in Portugal and Greece Sunday, with Spain and Italy sending reinforcements to Portugal to help battle a massive blaze burning for more than three days.
In Greece, authorities on Sunday urged residents of parts of Thessaloniki, the second largest Greek city, to remain indoors and shut their windows and doors due to toxic smoke from a burning recycling plant that was engulfed by a wildfire on the outskirts of the city.
