No L.A. threat, but still...

Osama bin Laden has aired a new threat against the U.S. on Al-Jazeera, and while it doesn't mention Los Angeles Mayor Villaraigosa has issued a reassuring statement anyway.

I have been fully briefed on the threat made by Osama Bin Laden and remain in close contact with the LAPD and other law enforcement agencies.

At this time there is no known direct threat to Los Angeles, but as always we remain vigilant and encourage our residents to do the same.

As a precautionary measure, the Los Angeles Police Department has deployed additional resources at LAX and posted signage indicating that bomb sniffing dogs and searches will occur frequently. A more visible police presence is also posted at LAX. The Port of Los Angeles and the Department of Water and Power have also been notified and will take additional precautionary measures as well.
