Five people were killed and dozens of others required medical treatment when a fire that apparently started in crop stubble spread through settlements in southeast Turkey overnight, officials said Friday.

The blaze erupted in an area between the provinces of Diyarbakir and Mardin. Fanned by winds, it moved quickly through the villages of Koksalan, Yazcicegi and Bagacik, Diyarbakir Gov. Ali Ihsan Su said. The fire was under control early Friday.
