As part of the State Department’s continuous efforts to provide Americans travelling abroad with information about relevant events, we are alerting U.S. citizens to the risk of potential terrorist attacks throughout Europe, targeting major events, tourist sites, restaurants, commercial centers and transportation. The large number of tourists visiting Europe in the summer months will present greater targets for terrorists planning attacks in public locations, especially at large events. This Travel Alert expires August 31, 2016.
France will host the European Soccer Championship from June 10 – July 10. Euro Cup stadiums, fan zones, and unaffiliated entertainment venues broadcasting the tournaments in France and across Europe represent potential targets for terrorists, as do other large-scale sporting events and public gathering places throughout Europe. France has extended its state of emergency through July 26 to cover the period of the soccer championship, as well as the Tour de France cycling race which will be held from July 2- 24.
The Catholic Church’s World Youth Day event is expected to draw up to 2.5 million visitors to Krakow, Poland, between July 26 and July 31. U.S. citizens should be aware that local infrastructure may be strained due to the large number of visitors. Poland will impose border controls at all of its national borders from July 4 to August 2, and visitors to Poland during this period should be prepared to show their passport and undergo stricter security screening throughout Poland. More information to help prepare for travel to World Youth Day can be found at https://pl.usembassy.gov/world-youth-day-2016/ and https://travel.state.gov/content/passports/en/go/youthday.html.
