This Public Announcement updates information on the continuing threat of terrorist actions and violence against Americans and interests overseas. This supersedes the Worldwide Caution dated April 10, 2007.  

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 and affiliated 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 assassinations, kidnappings, hijackings and bombings.  

Ongoing events in Iraq and elsewhere in the Middle East have resulted in demonstrations and associated violence in several countries. Americans are reminded that demonstrations and rioting can occur with little or no warning.

In August 2006, British authorities arrested a significant number of extremists engaged in a plot to destroy multiple passenger aircraft flying from the United Kingdom to the United States. The September 2006 attack on the U.S. Embassy in Syria and the March 2006 bombing near the U.S. Consulate in Karachi, Pakistan illustrate the continuing desire of extremists to strike American targets.  

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, clubs, restaurants, places of worship, schools, public areas and locales where Americans gather in large numbers, including during holidays. In August 2007, two bombs exploded almost simultaneously at an amusement park and a restaurant in India, killing at least 42 people. In June 2007, two unexploded car bombs were discovered in London. Financial or economic targets of value may also be considered as possible venues; the vehicle-based suicide attack on an oil facility near Mukalla and Marib in Yemen in September 2006 and the failed attack on the Abqaiq oil processing facility in Saudi Arabia in late February 2006 are such examples.  

In the wake of the August 2006 plot against aircraft in London, numerous terrorist attacks on trains in India in 2006, the July 2005 London Underground bombings, and the March 2004 train attacks in Madrid, Americans are reminded of the potential for terrorists to attack public transportation systems. In addition, extremists may also select aviation and maritime services as possible targets. In June 2007, a car was driven into the main terminal at Glasgow International Airport and burst into flames. The car bomb failed to detonate. 

U.S. Government facilities worldwide remain at a heightened state of alert. These facilities may temporarily close or periodically suspend public services to assess their security posture. In those instances, U.S. embassies and consulates will make every effort to provide emergency services to U.S. citizens. Americans abroad are urged to monitor the local news and maintain contact with the nearest U.S. embassy or consulate. 

As the Department continues to develop information on any potential security threats to U.S. citizens overseas, it shares credible threat information through its Consular Information Program documents, available on the Internet at http://travel.state.gov. In addition to information on the Internet, travelers may obtain up-to-date information on security conditions by calling 1-888-407-4747 toll-free in the U.S. and Canada or, outside the U.S. and Canada on a regular toll line at 1-202-501-4444.
