No casualties have been reported following the incident, according to Turkish news agency Dogan.
The agency said two missiles were fired from a mountainous area at the highway between the city of Antalya and the resort town of Kemer at around 10:30am on Friday, hitting a fishing company's shop.
Hurriyet newspaper said three rockets had been fired, and suggested the intended target of the attack may have been a tanker truck carrying fuel, not far from the shop.
Ambulance services and special forces police were sent to the scene, some 15 kilometers (9 miles) from Antalya, Dogan reported.
The motive of the attack remains unknown.
Authorities in Antalya released a statement saying: "This morning at 10:20am, an explosion occurred in the town of Antalya, Turkey at Çalticak Fishing Shelter. The cause of the explosion is being investigated."
