“The Department of State has issued this Worldwide Caution to update information on the continuing threat of terrorist actions and violence against U.S. citizens and interests throughout the world. U.S. citizens are reminded to maintain a high level of vigilance and to take appropriate steps to increase their security awareness. This replaces the Worldwide Caution dated January 24, 2012, to provide updated information on security threats and terrorist activities worldwide.
The Department of State remains concerned about the continued threat of terrorist attacks, demonstrations, and other violent actions against U.S. citizens and interests overseas. Current information suggests that al-Qaida, its affiliated organizations, and other terrorist organizations continue to plan terrorist attacks against U.S. interests in multiple regions, including Europe, Asia, Africa, and the Middle East. These attacks may employ a wide variety of tactics including suicide operations, assassinations, kidnappings, hijackings, and bombings.
Extremists may elect to use conventional or non-conventional weapons, and target both official and private interests. Examples of such targets include high-profile sporting events, residential areas, business offices, hotels, clubs, restaurants, places of worship, schools, public areas, and other tourist destinations both in the United States and abroad where U.S. citizens gather in large numbers, including during holidays.
U.S. citizens are reminded of the potential for terrorists to attack public transportation systems and other tourist infrastructure. Extremists have targeted and attempted attacks on subway and rail systems, aviation, and maritime services. In the past, these types of attacks have occurred in cities such as Moscow, London, Madrid, Glasgow, and New York City.”
