Two rockets landed near the Mediterranean resort of Antalya in Turkey hitting a pen ground and shelter used by a fishing company, said news reports. Nobody was harmed.
Dogan news agency said the rockets were fired from a mountainous area near a highway linking Antalya and the town of Kemer. The target of the attack may have been tanker truck carrying fuel, the agency said.
Several ambulances and fire-fighting trucks were sent to the scene, some 15 kilometers (9 miles) from Antalya, Dogan reported.
The motive for the attack in an area that is a major tourist destination was not known.
The Antalya governor's office confirmed that an explosion had occurred in the area and said an investigation was launched.
Turkey has been rocked by a spate of deadly attacks by Islamic State group militants or Kurdish rebels.
The country is still reeling from a failed military coup in July, blamed on the followers of U.S.-based Muslim cleric Fethullah Gulen.
Earlier reports said the target may have been a tanker ship moored at sea.
