Iran has increased its uranium enrichment capacity by at least 30% in the last four months, according to the latest quarterly report by the UN's International Atomic Energy Agency (IAEA). Iran has doubled production capacity at the Fordo nuclear site, the report says.
The IAEA also claimed that Iran has "significantly hampered" its ability to inspect the Parchin site. The site has been "sanitized," the agency charged, and Iran has been "conducting activities at that location that will significantly hamper the agency's ability to conduct effective verification", even if inspectors are allowed to enter it.
Iran has produced 189kg of higher-grade enriched uranium since 2010, up from 145kg, the agency added.
The number of enrichment centrifuges at the Fordo site, a facility buried inside a mountain near Qom, has more than doubled, from 1,064 in May to 2,140 at present, the IAEA said. The new centrifuges were not yet operating, it added.
