In a security warning sent to US citizens overnight, the US Embassy said Turkish police were investigating a "terror cell" in Gaziantep that could be targeting "shopping centres, Starbucks, Big Chef Restaurants" and other businesses in the city.
The warning did not specify the organisation that is under investigation.
Turkey has suffered a series of bombings by ISIS or Kurdish militants in the past year, including an ISIS attack on Istanbul's main airport.
At least 54 people were killed in a suicide bomb attack on a Kurdish wedding in Gaziantep last month. Authorities blamed the attack on ISIS militants.
