July 18, 2012
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.
