US Asks Citizens To Avoid Starbucks, Others In Turkish City

In a security warning sent to US citizens Thursday, the US Embassy said Turkish police were investigating a "terror cell" in Gaziantep that could be targeting "shopping centers, Starbucks, Big Chef Restaurants" and other businesses in the city.

The warning did not specify the organization that is under investigation.

Turkey has suffered a series of bombings by Islamic State group or Kurdish terrorist 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 terrorists.
