The U.S. State Department issued a new travel alert May 31. The alert addresses European travel in the upcoming summer months, as larger tourist numbers and popular events are cited as possible targets for terrorism. The State Department drew notice to the European Soccer Championship, June 10–July 10, and the Catholic Church’s World Youth Day celebration, July 26–July 31. France, which hosts the European Soccer Championship, extended its state of emergency through July 26 to cover both the event and the Tour de France, July 2–24. World Youth Day is expected to bring 2.5 million travelers to Krakow. In order to prepare for the event, Poland will impose strict border controls July 4–Aug. 2. U.S. citizens are advised to practice extra caution in public places, including public transportation, and to avoid crowded areas when possible. Obeying local authorities is recommended, as is keeping an eye on local media and news. Before traveling, create an emergency plan with fellow travelers and instruct non-traveling families and friends on how to reach you in the event of an attack.
