CHARLESTON, SC (WCSC) - United States airports and embassies are on alert for the heightened possibility of anti-American violence in the wake of Osama Bin Laden's death.
Despite the alert, travelers at Charleston International Airport Monday didn't seem overly concerned.
"I'm not afraid about flying. No, not at all," said Jack Anthony of North Charleston. "I fly all the time."
The U.S. State Department issued a worldwide travel alert for anyone headed overseas to areas prone to anti-American violence. U.S. embassies are also on high alert following the death of Bin Laden.
The state department is asking travelers to limit their travel especially if they are headed overseas.
President Barack Obama made the announcement late Sunday evening, saying that Bin Laden had been killed in Pakistan by American forces.
In Los Angeles, police were stepping up intelligence monitoring, while New York was sending extra police to its subways, airports, bridges and the World Trade Center site itself.
The Port Authority of New York and New Jersey said it will add more police at the facilities it runs, which include the airports, the George Washington Bridge and ground zero.
"This response is not based on a current threat, but out of an abundance of caution until we have the chance to learn more," the agency said.
Washington's Metro transit system also stepped up security.
New York Police Commissioner Ray Kelly issued a message to all police commands reminding them that while there's no information indicating a specific threat to the nation's biggest city, officers should remain alert.
He directed that the midnight tour in the subway system be held over into the morning rush-hour.
Police in Philadelphia were on heightened alert, checking on mosques and synagogues and stepping up patrols at transportation hubs and historic places, Lt. Raymond J. Evers said.
