Gov. Mehmet Ceylan said a sudden change of wind direction appeared to have caused the balloon which took off from Goreme to make a rough landing. The exact cause of the accident was under investigation, he added.
The injured tourists were hospitalized but were not in life-threatening condition, he said.
Dozens of hot air balloons carry tourists aloft most mornings in Goreme to watch the sunrise over the world-renowned landscape of geological formations in the area.
