The Department of State is updating the Worldwide Caution to provide 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 April 10, 2014.

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. On September 22, 2014, the United States and regional partners commenced military action against the Islamic State of Iraq and the Levant (ISIL), a designated  terrorist organization in Syria and Iraq. In response to the airstrikes, ISIL called on supporters to attack foreigners wherever they are. Authorities believe there is an increased likelihood of reprisal attacks against U.S., Western and coalition partner interests throughout the world, especially in the Middle East, North Africa, Europe, and Asia.

Kidnappings and hostage events involving U.S. citizens have become increasingly prevalent as ISIL, al Qa`ida and its affiliates have increased attempts to finance their operations through kidnapping for ransom operations. ISIL, al-Qa’ida in the Arabian Peninsula (AQAP) and al-Qa’ida in the Islamic Maghreb (AQIM) are particularly effective with kidnapping for ransom and are using ransom money to fund the range of their activities. Kidnapping targets are usually Western citizens from governments or third parties that have established a pattern of paying ransoms for the release of individuals in custody.

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, shopping malls, 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.
