From the Wall Street Journal:
WASHINGTON—U.S. investigators are probing whether a suspected terror plot against Western European targets extends to the U.S., officials said Tuesday. ...
The Central Intelligence Agency has stepped up drone strikes in Pakistan in an effort to help thwart the plot, which could still be evolving. The more than 20 strikes this month represent a monthly record, according to a tally by the New America Foundation.
Several U.S. officials said they haven't seen a terror threat as serious as the suspected European plot for many years. "This isn't just your typical Washington talk about how the threats have evolved. People are very concerned about what they're seeing," the counterterrorism official said.
While officials are still working to understand the plot, a leading concern is that the plotters may model their European assault on the 2008 attack in Mumbai, India, in which armed gunman killed more than 200 people in coordinated attacks at hotels and other easily accessed venues, current and former officials said.
