The U.S. government has determined that the Taliban in Pakistan was behind an attempted car bombing last weekend in Times Square, Attorney General Eric Holder said Sunday.

“We’ve now developed evidence that shows that the Pakistani Taliban was behind the attack,” Holder said during an appearance on ABC's “This Week.”

Holder's remarks contrast with what other cabinet secretaries had said last Sunday, when officials had first discovered the attempted attack. Homeland Security Secretary Janet Napolitano described the attack as "one off."

But Holder said that Faisal Shahzad, the Pakistani-born naturalized American citizen who's suspected in the attack, was working at the direction of the Taliban.

"We know that they helped facilitate it," the attorney general said. "We know that they probably helped finance it. And that he was working at their direction.”

Shahzad was arrested late Monday evening at a New York airport, where he was attempting to travel to Dubai. Since then, Shahzad has been said to be yielding valuable intelligence for U.S. officials.
