According to today's Telegraph (p24), the reason that new "Khomeini" Airport in Tehran was closed so quickly after its opening was not, as stated at the time, a dispute with the Austrian/Turkish builders, but because of a nuclear accident caused by material being imported from North Korea.
According to the reports, Revolutionary Guard fighter aircraft escorted aircraft away from the new airport (including one which was low on fuel). Although the airport "opened" (briefly) to commercial traffic this year, it was being used by military aircraft for some time. During one of these incidents, material being offloaded from a North Korean military transport, fell onto the apron and leaked; this incident went unreported. The Revolutionary Guards won't allow the airport to be opened for fear there is any trace of nuclear materials; foreign nationals (and particularly, UN inspectors) are not being allowed anywhere near the airport.
I guess spotting is out, then?
