The Turkish holiday resort region of Antalya is reported to have come under rocket attack.
The local Hurriyet newspaper said three rockets were fired, and they hit a shelter used by fishermen.
It said a tanker moored off shore may have been the intended target.
Ambulances and special forces police have been sent to the area although no-one is thought to have been injured.
The rockets were reportedly fired from a mountainous area near a road linking the city of Antalya and the resort town of Kemer.
The province of Antalya is next to the popular tourist areas of Marmaris and Bodrum, and just north of Cyprus.
The motive for the attack is unknown, but Turkey has been hit by a spate of deadly attacks by both Islamic State militants and Kurdish rebels.
A failed military coup in the country in July was blamed on followers of the Muslim cleric Fethullah Gulen, who is based in the US.
The Foreign and Commonwealth Office confirmed that a rocket attack took place in Antalya.
“No casualties were reported,” the FCO said.
There were also attacks against the Turkish military in Van, Hakkari, Diyarbakir and Adiyaman, resulting in 13 injuries to service personnel.
