Wildfires that have engulfed Turkey for weeks threatened the country’s fourth-largest city early Sunday, causing more than 1,700 people to flee their homes and leaving a firefighter dead.

Firefighters battled blazes across Turkey and Bulgaria on Monday as a deadly heatwave went into a second week around much of the Mediterranean.Last week, one wildfire killed at least 10 forest workers and rescuers fighting a blaze near Eskisehir in western Turkey.
