Forest fire rages near popular Turkish resort
"It's an unbelievably bad sight," Manavgat mayor Sukru Sozen told CNN Turk.
Local officials said four districts of the town had been evacuated and the fire was partially under control.
It was not immediately clear how many people had been affected but NTV television said 20 buildings housing around 500 people had burned down in one part of the town.
The Anadolu state news agency denied initial reports that a local hospital had been evacuated as a precaution.
"Thankfully, we have had no losses of life," Bocek told NTV television. Flames appeared to have erupted at four locations at once, he added.
"This suggests an arson attack, but we do not have clear information about that at this stage."
Agriculture Minister Bekir Pakdemirli confirmed that fires had started in four locations but said it was premature to say what had caused the blaze.
Winds of up to 50 kilometres an hour (30 mph) were fanning the flames, he added.
"Our job now is to fight the fire," the minister said in televised remarks. "There will be an investigation and the causes will be determined later."
