The US State Department has put US embassies on alert and warned of the heightened possibility for anti-American violence after the killing of al Qaida leader Osama bin Laden by American forces in Pakistan.
In a worldwide travel alert released shortly after President Barack Obama announced bin Laden's death in a US military operation, the department said there was an "enhanced potential for anti-American violence given recent counter-terrorism activity in Pakistan".
"Given the uncertainty and volatility of the current situation, US citizens in areas where recent events could cause anti-American violence are strongly urged to limit their travel outside of their homes and hotels and avoid mass gatherings and demonstrations," it said.
The alert said US embassy operations would continue "to the extent possible under the constraints of any evolving security situation".
It noted that embassies and consulates may temporarily close or suspend public services, depending on conditions.
