Turkey Travel Warning
The U.S. Department of State warns U.S. citizens of increased threats from terrorist groups throughout Turkey and to avoid travel to southeastern Turkey. Effective March 29, 2016, the Department of State ordered the departure of family members of U.S. government personnel posted to U.S. Consulate in Adana and family members of U.S. government civilians in Izmir and Mugla provinces, and restricted official travel to Turkey to “mission-critical” travel only. U.S. Consulate in Adana remains open and will provide all routine consular services. This Travel Warning replaces the Travel Warning dated March 17, 2016.
Foreign and U.S. tourists have been explicitly targeted by international and indigenous terrorist organizations. U.S. citizens are reminded to review personal security plans and remain vigilant at all times. U.S. government personnel in Turkey remain subject to travel restrictions in southeastern provinces of Hatay, Kilis, Gaziantep, Sanliurfa, Sirnak, Diyarbakir, Van, Siirt, Mus, Mardin, Batman, Bingol, Tunceli, Hakkari, Bitlis, and Elazig. U.S. citizens should avoid areas in close proximity to the Syrian border.

Avoid travel to southeastern Turkey, particularly near the Syrian border.

Exercise heightened vigilance and caution when visiting public access areas, especially those heavily frequented by tourists.
Stay away from political gatherings and rallies.
