Did the IAEA miss something?

Given the IAEA's knack for missing the existence of and important developments in Iran's nuclear program, how much credence should we give their claim that there was no explosion at Fordow?

The International Atomic Energy Agency (IAEA), in an unusual move, made a brief statement following media reports at the weekend of significant damage at the underground Fordow uranium enrichment site.

IAEA inspectors regularly visit Iranian nuclear sites, including the one at Fordow, and the UN agency suggested in its comment that they had been at the site after the reports in some Israeli and Western media of an explosion there.

"We understand that Iran has denied that there has been an incident at Fordow. This is consistent with our observations," IAEA spokeswoman Gill Tudor said in an emailed comment in response to a question.

Hmmm.
