The Department of State is issuing this Travel Alert to caution U.S. citizens of the potential for anti-U.S. demonstrations in many countries in response to stated plans by a church in Florida to burn Qur'ans on the anniversary of the September 11, 2001 terrorist attacks. Demonstrations, some violent, have already taken place in several countries, including Afghanistan and Indonesia, in response to media reports of the church's plans. The potential for further protests and demonstrations, some of which may turn violent, remains high. We urge you to pay attention to local reaction to the situation, and to avoid areas where demonstrations may take place. This Travel Alert expires on September 30, 2010.
We also remind you of the continuing threat to U.S. interests and citizens posed by various terrorist groups, as outlined in the Department's Worldwide Caution.
U.S. citizens living or traveling abroad are encouraged to register with the nearest U.S. Embassy or Consulate through the State Department's travel registration website at in order that they can obtain updated information on travel and security. U.S. citizens without Internet access may register directly with the nearest U.S. Embassy or Consulate. By registering, U.S. citizens make it easier for the Embassy or Consulate to contact them in case of emergency.
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. U.S. citizens abroad are urged to monitor the local news and maintain contact with the nearest U.S. Embassy or Consulate.
As the Department of State continues to develop information on potential security threats to U.S. citizens overseas, it shares credible threat information through its Consular Information Program documents, such as the Worldwide Caution, Travel Warnings and Travel Alerts as well as Country Information, which are available on the Bureau of Consular Affairs website 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 United States and Canada or, outside the United States and Canada, on a regular toll line at 1-202-501-4444. These numbers are available from 8:00 am to 8:00 pm Monday through Friday, Eastern Time (except U.S. federal holidays).
