Firefighters in Greece struggle to control wildfires, including the EU's largest blaze

[Collection]Firefighters struggled Thursday against strong winds and hot, dry conditions to tame multiple wildfires ravaging Greece, including one in the country's northeast that officials say is the largest recorded in the European Union. The wildfires have left 20 people dead over the last week. Eighteen of those, including two boys aged between 10 and 15, are believed to be migrants who crossed the nearby border with Turkey.
