FBI: No al-Qaeda threat to U.S.

Five weeks after Navy Seals snatched terabytes of data from Osama bin Laden's Pakistani lair, counterterrorism officials in Philadelphia say they've received no specific warnings of expected attacks inside the United States.

"We haven't seen anything filtering down in terms of evidence that there's a plan in place or that anyone is targeting specific landmarks," FBI Special Agent in Charge George Venizelos said.

Another official said the vast majority of the bin Laden data concerned Pakistan and Afghanistan, not the United States.

But, Venizelos added, "What it definitely shows is that al-Qaeda's commitment to attack has not gone away - and you have to be careful of people, lone wolves living here inspired by him looking to avenge bin Laden's death."

In the days after the raid, U.S. officials said al-Qaeda planned to target public transit, specifically the rails.

SEPTA spokeswoman Jerri Williams said the agency hadn't reduced the elevated status it enacted May 2, which includes extra K-9 and SWAT-style patrols in Center City.

"We are continuing to get bulletins, but we have not been advised of any threats to public transportation beyond what we learned last month," she said.

Officials and agents of other agencies also reported no new, specific threats or shifts in staffing. Said one counterterrorism agent, "For us, it's business as usual."
