In a worldwide travel alert released shortly after President Barack Obama late on Sunday announced bin Laden's death in a military operation, the department said there was an "enhanced potential for anti-American violence given recent counterterrorism activity in Pakistan."
It said Americans living or traveling abroad, particularly in areas that have been hit by anti-American violence in the past should limit travel outside their homes and avoid large gatherings.
The alert said US embassy operations would continue "to the extent possible under the constraints of any evolving security situation."
