Washington As the United States began military action Sunday against targets in Afghanistan, the State Department warned of the possibility of "strong anti-American sentiment and retaliatory actions against U.S. citizens and interests throughout the world."
These actions may be taken "by terrorists and those who are sympathetic to or otherwise support terrorism," the department said in issuing a "worldwide caution."
Americans in Afghanistan, which harbors Osama bin Laden, chief suspect in the Sept. 11 terrorist attacks against the United States, should depart the country, the government said.
Americans elsewhere were urged to monitor the local news, stay in touch with the nearest U.S. embassy or consulate and limit their movement.
The latest travel information can be obtained from the State Department's Web site, at travel.state.gov, as well as the Web sites of U.S. embassies and consulates.
