The United States on Monday warned its citizens of a potential security threat targeting US-branded hotels in southern Turkey, a US consulate said in a statement.
The consulate in southern Adana province said on its website that "it has obtained specific and credible threats of potential terrorist activity targeting US-branded hotels in Adana."
It advised US citizens in Adana "to exercise caution when patronizing these establishments."
Adana hosts Incirlik air base — used by the US-led coalition for air strikes against the Islamic State group in Syria.
The US embassy last week warned of the risk of a terror attack in another Turkish city of Gaziantep close to the Syrian border on businesses frequented by Westerners, including the popular coffee chain Starbucks.
Turkey has been the target of a string of attacks blamed on Kurdish militants or the IS group.
A suicide bombing at a Kurdish wedding in Gaziantep last month killed 57 people, 34 of them children, and was blamed by Turkish authorities on IS jihadists.
