You would have to be living in a cave buried deep in Pakistan to not have heard the most incredible news of the past decade — worldwide master terrorist, Osama bin Laden, is dead. He was killed in a covert operation carried out by the US military on Sunday night. The country is still rejoicing and will continue to.

Along with massive US celebration over the news, an alert has been issued. The alert, posted on AOL Travel reads: “Given the uncertainty and volatility of the current situation, U.S. 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. U.S. citizens should stay current with media coverage of local events and be aware of their surroundings at all times.”

Americans overseas were further encouraged by the Department of State to stay in frequent contact with family/friends back home. It was also recommended they register their travel with the Department of State’s Smart Traveler Enrollment Program.  Americans aren’t the only travelers urged to use caution. Alerts have also been issued for citizens, particularly Britains and Australians in Indonesia, the world’s most heavily populated Muslim country.

Retaliation is anticipated, and could be on both large and small scales. Typical targets would include areas of mass transportation, diplomatic or otherwise “symbolic” centers.

So in a time where most of the world is celebrating that they might sleep a little bit safer tonight, continue with caution on the road and with your fellow man. Travel with vigilance.
