Video Threats Against L.A. Surface

Purported Al Qaeda Tape Dismissed By Police As 'Rhetoric'

Bratton said Los Angeles officials are no strangers to terrorist threats. Being one of the top three target cities in America, the City of Angels is always on guard, he told CBS News.

"Within the last two weeks we broke up a home-grown terrorist cell emanating in one of our state prisons," Bratton said. "We're as concerned with the home-grown terrorist plots as we are with the international terrorist plots."

While no steps are planned in response to the video, he said, the city is always on the lookout for terrorists and plans heightened security measures in upcoming days because of the Jewish high holidays.

"The statement was meant to instill fear, and fear is the most potent weapon the terrorists posses," Bratton and Mayor Antonio Villaraigosa said earlier in a statement. "Bombastic pronouncements are expected on the eve of terrorist incidents like September 11, but we cannot let such pronouncements alter our lifestyles."

Australian Attorney General Philip Ruddock said the threat was being taken seriously, although the nation's security threat level remained unchanged at medium.

"The best response to things like this is to redouble our protective efforts, which we are doing, but also to get on with life, which we are also doing," said Australian Prime Minister John Howard.

In May 2004, the U.S. government announced that Gadahn was suspected of attending an al Qaeda training camp and working as a translator for the group. Investigators have said that Gadahn, who grew up on a farm in California, converted to Islam as a teen and moved to Pakistan.

A phone listing for Gadahn's father, Philip Gadahn, could not be found Sunday. Gadahn's aunt, Nancy Pearlman, said she had seen news coverage of the video but the family had no comment.

Last year Philip Gadahn said that he was baffled by the allegation his son was an al Qaeda operative, saying he has spoken to his son only occasionally in recent years but still can't imagine that he would be involved with a terrorist network.

Pakistan's Interior Minister Aftab Khan Sherpao said that authorities in his country "naturally inquire when such a tape appears, to know who delivered it or how." He said he had no information about whether Gadahn could be hiding in Pakistan.
