The UK Foreign Office has issued an urgent travel warning for Turkey, urging tourists to exercise caution due to ongoing security and health concerns. Visitors are advised to avoid non-essential travel to specific regions near the Syrian border, including Sirnak city and Hakkari Province, due to heightened risk of terrorism and military activity. The advisory also highlights the importance of adhering to health and safety guidelines, including practicing good hygiene to prevent gastric illness, and seeking medical attention for dog bites. Tourists engaging in activities like quad biking or water sports are reminded to obtain appropriate insurance and follow local regulations for safety.
