…a videotape of a “mock-up chamber and internals” of the missile re-entry vehicle, as well as laboratory preparations to test them, which could only have been obtained from sources inside Iran.
He also showed an Iranian animation demonstrating how a Shahab-3 missile could be programmed to detonate at about 2,000 feet over a target. Heinonen noted that detonation at that altitude only made sense for a nuclear warhead.
Key to the clandestine programs was a private Iranian company called Kimia Maadan, which the Iranians acknowledged had been set up in May 2000 to work on a secret uranium mine at Gachine.
Kimia Maadan was run by Revolutionary Guards Brig. Gen. Mohsen Fakhrizadeh, one of a number of alleged nuclear weapons designers the IAEA has sought to interview, without success.

Information on the construction of what appeared to be a nuclear test site, with a 1,300 foot shaft connected to a monitoring station six miles away, which the Iranians claimed was used to test conventional explosives.
