The shooting struck north of Tarsus, about 40 kilometres (25 miles) northeast of Mersin, prompting a widespread police manhunt to locate the shooter that also involved helicopters, it said.
DHA said the shooter was a 17-year-old armed with a shotgun.
The violence came a month after two shooting attacks by teenagers rocked Turkey.
In the first incident, 16 people were injured, while the second attack claimed 10 lives, most of them young school children.
