Four people, including two soldiers and a policeman, have been killed in Turkey in a shooting attack in the southern province of Nigde.
The incident occurred on Thursday when unidentified gunmen opened fire on security forces in the town of Ulukisla.
The men armed with long-range shotguns started shooting from a truck.
They reportedly killed a driver and escaped in his truck after they were ordered to stop at a checkpoint.
Turkey’s Prime Minister Recep Tayyip Erdogan condemned the attack and described the shooting as a "vile act of terror."
Turkish police have arrested two of the three men while the third shooter is still on the run.
According to Nigde Governor Necmeddin Kilic the men were foreign nationals but he gave no details on their nationalities.
Turkish media reports say the gunmen had entered Turkey through the Syrian border.
Hundreds of people gathered there to protest the attack as the suspects were transferred to a hospital under guard.
The protesters were dispersed by the police.
Turkey, a fierce opponent of Syrian President Bashar al-Assad's government, is seen as one of the major regional supporters of foreign-backed militants fighting government forces in Syria, along with Qatar and Saudi Arabia.
