Senior U.S. officials say the United States has obtained evidence showing that the Pakistani Taliban directed the plot behind the attempted car bombing in New York City's Times Square.
"The Pakistani Taliban has directed this plot," Attorney General Eric Holder said on May 9 in an interview on ABC television's "This Week."
"We know that they helped facilitate it, we know that they helped direct it. And I suspect that we are going to come up with evidence that shows they helped to finance it. They were intimately involved in this plot."
Holder said there was nothing to suggest that the government of Pakistan was aware that Faisal Shahzad, a naturalized U.S. citizen who was born in Pakistan, was planning to carry out the bombing.
In an interview with the "60 Minutes" television program, U.S. Secretary of State Hillary Clinton warned of "very severe consequences" if a successful terrorist attack against the United States was traced back to Pakistan.
She gave no further details about the consequences, but urged Pakistani authorities to do more to battle extremists.
Shahzad was arrested one week ago, two days after authorities say he parked a crude car bomb in New York's Times Square. The bomb failed to detonate and no one was injured.
U.S. officials say Shahzad has told investigators he received training in the Waziristan area of Pakistan, where both the Taliban and Al-Qaeda operate.
