Other countries have issued warnings, too.
The State Department alerts U.S. citizens to potential risks of travel to and throughout Europe following several terrorist attacks, including the March 22 attacks in Brussels claimed by ISIL. Terrorist groups continue to plan near-term attacks throughout Europe, targeting sporting events, tourist sites, restaurants, and transportation. This Travel Alert expires on June 20, 2016.
U.S. citizens should exercise vigilance when in public places or using mass transportation. Be aware of immediate surroundings and avoid crowded places. Exercise particular caution during religious holidays and at large festivals or events.
U.S. citizens should also:
Follow the instructions of local authorities, especially in an emergency.
Monitor media and local information sources and factor updated information into personal travel plans and activities.
Be prepared for additional security screening and unexpected disruptions.
Stay in touch with your family members and ensure they know how to reach you in the event of an emergency.

European governments continue to guard against terrorist attacks and conduct raids to disrupt plots. We work closely with our allies and will continue to share information with our European partners that will help identify and counter terrorist threats.
