This is a little disconcerting. The London Sunday Times claims that the FBI denied the existence of a document whose existence the Times later claims to have confirmed. The document in question allegedly regards an investigation of a Turkish and Israeli nuclear-secrets smuggling scheme: one in which American officials are alleged to have taken part.
So far there has been no mention of this in the American press, from what I can see. Not sure what’s going on here, but I think the activities involved are serious enough to warrant further investigation.
