U.S. counterterrorism officials say the Times Square plot is a possible signal that militant leaders in Pakistan have shifted focus to targets in the U.S. and the West instead of sticking to their home base.
The officials are warning that the failed attack in New York City could be only the first attempt by terrorist groups that are seeking to avoid detection by using simpler methods that are more independently planned.
The officials spoke on condition of anonymity because they aren't authorized to discuss the case publicly.
Investigators are trying to establish whether accused bomber Faisal Shahzad was trained or recruited for the operation by any Pakistan-based terrorist organization, including the Pakistani Taliban.
