Los Angeles Mayor Antonio Villaraigosa has responded to an audiotaped threat made by Osama bin Laden by increasing security at Los Angeles International Airport.

The Central Intelligence Agency (CIA) confirmed that an audiotape that aired on the Al Jazeera satellite television channel Thursday, January 19th, contained the voice of bin Laden.

Bin Laden said on the tape that Al Qaeda is preparing to attack the United States, but that the attacks could be avoided if the U.S. military leaves Iraq and Afghanistan.

CIA officials believe the tape was made in December 2004, indicating that bin Laden may still be alive.

“I have been fully briefed on the threat made by Osama bin Laden and remain in close contact with the Los Angeles Police Department and other law enforcement agencies,” Villaraigosa said.

As a precautionary measure, the police department has deployed additional resources at LAX and posted signage indicating that bomb-sniffing dogs and searches will occur more frequently.

A more visible police presence is also posted at the airport.

The Port of Los Angeles and the Department of Water and Power have also been notified and will take additional precautionary measures as well.

“We are fortunate to have strong relationships between local, state, and federal agencies through the Joint Terrorism Task Force,” Villaraigosa said.

“I am confident that law enforcement is coordinating and communicating information to detect and prevent terrorism here in Los Angeles,” he said.
