Exercise increased caution in the United Kingdom due to terrorism.

Terrorist groups continue plotting possible attacks in the United Kingdom. Terrorists may attack with little or no warning, targeting tourist locations, transportation hubs, markets/shopping malls, local government facilities, hotels, clubs, restaurants, places of worship, parks, major sporting and cultural events, educational institutions, airports, and other public areas.

There is also a risk of isolated violence by dissident groups in Northern Ireland, focused primarily on police and military targets.

Read the Safety and Security section on the country information page.

If you decide to travel to the United Kingdom:

• Be aware of your surroundings when traveling to tourist locations and crowded public venues.
• Follow the instructions of local authorities.
• Monitor local media for breaking events and adjust your plans based on new information.
• Enroll in the Smart Traveler Enrollment Program (STEP) to receive Alerts and make it easier to locate you in an emergency.
• Follow the Department of State on Facebook and Twitter.
• Review the Crime and Safety Report for the United Kingdom.
• U.S. citizens who travel abroad should always have a contingency plan for emergency situations. Review the Traveler’s Checklist.
