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.
EUROPE: Credible information indicates terrorist groups such as ISIL/Da’esh, and al-Qa’ida and affiliates continue to plot attacks in Europe as foreign fighters return home from Syria and Iraq, while other individuals may be radicalized or inspired by ISIL propaganda. In the past year extremists have carried out attacks in France, Belgium, Germany and Turkey. European authorities continue to warn of additional attacks on major events, tourist sites, restaurants, commercial centers, places of worship, and the transportation sector. All European countries remain vulnerable to attacks from transnational terrorist organizations and U.S. citizens are urged to exercise vigilance while in public places.
