The second major blast in Iran recently was reported to be at a nuclear site. Times of London reports now it was a missile site not a nuclear site but a chemical processing facility where UF6 is built for later enrichment.
The first blast in Iran that made the headlines, occurred two weeks ago in Bidganeh. It is now clear that this explosion took place on an air force base during tests with a long range missile, probably a Sjejjil 3 intercontinental ballistic missile.
This has been confirmed by Mohammed Teherani Moghaddam the brother of the senior Revolutionary Guard commander who was in charge with the Iranian missile defense, and who was killed in the explosion. So the first blast didnít involve any nuclear facility.
As for the uranium enrichment facility. There is no such facility in Isfahan. Isfahan is a conversion plant where yellowcake is converted to hexafluoride, or UF6, and other compounds. This is then sent to Natanz, where the enrichment takes place.
The idea that the Mossad or another foreign intelligence agency would target Isfahan and not Natanz, does not seem to be logical at all.
