WASHINGTON — A senior U.S. military official says Pakistan now has at least two men in custody on suspicion of helping to finance the Times Square bombing attempt.

The investigation into the May 1 attempt has widened as authorities in the U.S. and Pakistan follow the money trail.

The official spoke on condition of anonymity to The Associated Press to discuss the sensitive issue of Pakistani cooperation in the probe.

The AP and other news organizations had previously reported that Pakistan had one man in custody.

It is not clear whether the two are members of the Pakistani Taliban, which U.S. authorities say was behind the plot.
