Airports on alert for Osama anniversary

INDIANAPOLIS (WISH) - It was one year ago Tuesday night that U.S. Navy Seals killed Osama Bin Laden. The anniversary has security officials around the country on alert.

So far, federal officials have not said anything about a specific threat, but they said they will have extra eyes at airports and on board flights in Indianapolis and around the United States.

One main concern moving forward is that terrorists will try a new tactic.

With heightened screening since Sept. 11, terrorism experts said they believe terrorists could try to swallow or implant an explosive on their body rather than carry explosives on board.

The Department of Homeland Security released a statement Monday that said, although threats from al Qaeda and other terrorist groups continue to evolve, there is "no indication of any specific, credible threats or plots against the U.S. tied to the one-year anniversary of bin Laden's death."

But one official said federal authorities use extra caution around the anniversary because of the potential for retaliation.

At Indianapolis International Airport, airport officials estimate that 135 flights take off each day.

It’s estimated that over half a million people pass through the airport each month.
