Iran’s diplomatic spokesperson denounced an IAEA Board of Governors resolution on Iran’s lack of safeguards cooperation as “miscalculated and ill-advised” and warned: “The initiators are responsible for the consequences. Iran’s response is firm and proportionate”. The same day, the Atomic Energy Organisation of Iran (AEOI) issued a statement asserting that “Iran has so far had extensive cooperation with the IAEA, but unfortunately having failed to consider such cooperation which has derived from Iran’s goodwill, the Agency has not appreciated it, and instead has considered it a duty”. In response, the statement read, Iran “decided that the operation of the cameras of the On-Line Enrichment Monitor (OLEM) and the IAEA’s flow meter should be stopped from today”. The same day, the IAEA reported that “Iran had started to install IR-6 centrifuges in the… single cascade previously declared by Iran” at Natanz, with intentions to install two more. Iran subsequently confirmed injecting fuel into the installed cascade.
