Hundreds of firefighters battled wildfires in Portugal, Greece and Spain on Sunday, with Spain and Italy sending reinforcements to Portugal to help with a massive blaze burning for more than three days.
Authorities urged residents in parts of Thessaloniki, Greece's second largest 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. Another major wildfire broke out Sunday afternoon west of the Greek capital, Athens.
