Wildfires that have engulfed Turkey for weeks threatened the country’s fourth-largest city early Sunday, causing hundreds of people to flee their homes. Overnight fires in the forested mountains surrounding Bursa in northwest Turkey spread rapidly, bringing a red glow to the night sky over the city’s eastern suburbs. Bursa governor’s office said in a statement Sunday that 1,765 people had been safely evacuated from villages to the northeast as more than 1,100 firefighters battled the flames.
