The International Atomic Energy Agency, after inspecting the recently disclosed nuclear facility at Qom, suspects there may be more:
International inspectors who gained access to Iran’s newly revealed underground nuclear enrichment plant voiced strong suspicions in a report on Monday that the country was concealing other atomic facilities. [...]
