Wildfires rage in Portugal, Greece and Spain while Greek authorities warn of toxic smoke

Large wildfires are raging across Portugal, Greece and Spain, with Spain and Italy sending reinforcements to help Portugal battle a massive blaze.
A recycling-plant fire near Thessaloniki sent toxic smoke over suburbs, forced evacuations and led authorities to urge people to stay indoors; a man was arrested on suspicion of starting it.
Greek officials say about 85% of wildfires are caused by negligence, and the country is increasingly using aircraft and new satellites to detect and fight fires.
