Anniversary of bin Laden's Death Prompts Heightened Security Alerts at Southland Airports

Security was expected to be on heightened alert at Los Angeles International Airport and other Southland airports for tomorrow's one-year anniversary of the death of al-Qaida leader Osama bin Laden, and in response to reports that terrorist organizations may try to use surgically implanted bombs to bypass security checks.

Los Angeles World Airports, the city agency that operates LAX and airports in Ontario and Van Nuys, issued a statement saying that while no specific threats have been received, "we will continue to maintain vigilance and uphold our constant security posture to ensure the airport and the traveling public are safe ...

"LAWA will continue to monitor global events and stay in direct contact with our federal, state and local partners," according to the statement.

Various media reports out of Washington, D.C., stated that security has been stepped up at airports in Europe and the Middle East, and federal air marshals had been deployed overseas in advance of the anniversary of bin Laden's death.

U.S. and European authorities have been warning for the past year that al-Qaida operatives have been working to design non-metal explosives that can be surgically implanted so the carrier can slip unnoticed through airport security.

Department of Homeland Security officials insisted there was no specific threat of an attack.

"We have no indication of any specific, credible threats or plots against the U.S. tied to the one-year anniversary of bin Laden's death," DHS spokesman Peter Boogaard told ABC News.
