State Department security wasn't totally at ease on this year's anniversary of 9/11, when terrorists stormed the U.S. facility in Benghazi, Libya, killing the ambassador and others to the surprise of Washington.

While the department dismissed concerns in the Middle East of a copycat attack, they did issue a warning to workers in Chile, a key ally in South America. The reason: September 11 is the anniversary of the 1973 coup against Salvador Allende that installed Gen. Augusto Pinochet.

"Each year the anniversary is marked by demonstrations, marches, and protests, usually in downtown Santiago near government buildings and some outlying communities of the Metropolitan Region," said a State warning.

"Demonstrations could begin as early as noon on the 11th and are expected to continue into the evening. As these demonstrations can turn violent, U.S. citizens should monitor the media for the latest information on the locations of the demonstrations and to avoid those areas," State added in a "security message" issued September 10, according to blogger Jeryl Bier's site Speak With Authority.

Security Message for U.S. Citizens: Potential September 11th Violence

U.S. Embassy Santiago, Chile

September 10, 2012

September 11th marks the anniversary of Chile's 1973 coup against the government of Salvador Allende, establishing military rule from 1973 - 1990 (led by General Augusto Pinochet, who died in 2006). Each year the anniversary is marked by demonstrations, marches, and protests, usually in downtown Santiago near government buildings and some outlying communities of the Metropolitan Region.

Demonstrations could begin as early as noon on the 11th and are expected to continue into the evening. As these demonstrations can turn violent, U.S. citizens should monitor the media for the latest information on the locations of the demonstrations and to avoid those areas. The demonstrations will affect transportation services in some areas.

We wish to remind U.S. citizens that even demonstrations intended to be peaceful can turn confrontational and possibly escalate into violence. U.S. citizens are therefore urged to avoid the areas of demonstrations if possible, and to exercise caution if within the vicinity of any demonstrations.

U.S. citizens living or traveling in Chile are encouraged to enroll in the Smart Traveler Enrollment Program (STEP) through the U.S. Embassy website. By enrolling, you make it easier for the embassy to contact you in case of emergency. U.S. citizens without internet access may enroll directly at the U.S. Embassy in Santiago, located at Avenida Andres Bello 2800, telephone 011 (56)(2) 330-3000, e-mail SantiagoAmcit@state.gov.
