More from Islamabad:
An intelligence official who was not authorized to speak on the record said two arrests had been made in Karachi in connection with the bombing attempt. One arrested is named Tausif Ahmed, and he is believed to have traveled to the United States recently to meet with Shahzad, according to this official. The official did not have the other’s name. Ahmed was arrested in a busy commercial neighborhood called Gulshan-e-Iqbal.
Pakistani television stations are reporting that as many as five other connected people may have been arrested in the central industrial city of Faisalabad, but those reports are not confirmed.
Shahzad hails from Pabbi, the main town of Nowshera District in the northwest, near Peshawar, according to Interior Minister Rehman Malik.
