The news begins anew with "Studio B"...

Trying to prevent what happened in London from happening in New York City, law enforcement has stepped up security on subways after receiving credible threats. Officials say terrorists are not planning a "spectacular" event like the attack on the World Trade Center, but rather a series of strikes similar to the transit bombings in London this summer. We'll get the latest from former NYC Police Commissioner Howard Safir.

Then, Karl Rove (search), the White House deputy chief of staff and longtime adviser to President Bush, agrees to testify again on the leak of a CIA officer's name without protection against indictment. We'll get the legal breakdown from Judge Andrew Napolitano, FOX News' senior judicial analyst.

And, bomb blasts kill six Marines in western Iraq and U.S. forces kill 29 militants in U.S. offensives aimed at uprooting Al Qaeda (search) insurgents ahead of the country's vote on a new constitution. We'll have the details.
