Pakistan eyes Afghan link in foiled London plot

"So far, all agencies have failed to break [Mr. Rauf] in identifying the Afghan national who works as a frontline man of Al Qaeda," says an intelligence official, speaking anonymously.

Casting some doubt on any Afghan connection are the facts that Pakistan and Afghanistan frequently exchange accusations and the possibility that Rauf may be saying what his Pakistani interrogators want to hear.
