Germans say 6 companies sold nuclear parts to Iran Network

I picked an article called " Germans Say 6 Companies Sold Nuclear Parts to Iran Network". I found this article to be intriguing because Germany is trying to find out who exported or shipped 3.6 million worth of nuclear equipment. Germany has this restrictions about shiping equipment to other countries, and to Iran it's borbidden. So somehow they think that may be there is a Russian middlemen, because since the equipment cannot come to Iran but can come to any other country like Russia, (which is close to Iran) so they assumed that may be nuclear parts went there and then to Iran. This article reminds me of Nicholas Cage movie about guns. Now i am curious who actually shipped the equipment. Russian authorities say that they don't know anything about this. Iran says that they are innocent also. NOT FUN......
