"Take a closer look at the sourcing in the original New York Times piece disclosing Khan's name, which was written by Douglas Jehl and David Rohde. They cite a "senior United States official" for details on the documentary evidence found after the capture of a suspect, but this "United States official" is pointedly not cited as having given the name of the suspect. Instead, a few paragraphs further down, the Times reporters tell us:
The American officials would say only that the Qaeda figure whose capture had led to the discovery of the documentary evidence had been captured with the help of the C.I.A. Though Pakistan announced the arrest last week of a Qaeda member, Ahmed Khalfan Ghailani, a Tanzanian wanted in connection with the bombings of American embassies in East Africa in 1998, the American officials suggested that he had not been the source of the new threat information.
An account provided by a Pakistani intelligence official made clear that the crucial capture in recent weeks had been that of Mr. Khan, who is also known as Abu Talha. The intelligence official provided information describing Mr. Khan as having assisted in evaluating potential American and Western targets for terrorist attacks, and as being representative of a ''new Al Qaeda.''
