Sorry but frankly I do not believe him - I've not forgotten all the times during the Afghan saga when he made similar statements as to things being confirmed/verified and turned out he was talking complete rubbish. Never mind many other things he has come out with such as claiming to have visited a synagogue when he didn't, claims to have been arrested when he wasn't, claiming to have worked for a company where the owner is categoric that he didn't and so on. The man is not a reliable source for verified information which is shameful for the post.
EDIT: That isn't to say the incident did or didn't happen, that is another story again and as I've mentioned I've seen verified accounts of similar things happening during these events.
