According to consular sources, the risk of terrorist attacks is elevated at churches, synagogues, and diplomatic missions in Istanbul or other places Westerners frequent, especially in the Beyoglu, Galata, Taksim, and Istiklal areas. Extreme vigilance is recommended. Travelers should maintain a high level of security awareness, follow the advice of local authorities, carry a fully charged communication device, and monitor the situation through local media and embassy communications.
