IAEA chief Rafael Grossi's comments appear to support an early assessment from the Pentagon’s Defense Intelligence Agency.

Overview

  • Iran’s parliament has suspended cooperation with the IAEA, banned its director general from nuclear sites and ordered the removal of surveillance cameras.
  • Iran’s UN ambassador, Amir-Saeid Iravani, has offered to send its existing stockpiles of 20% and 60% enriched uranium abroad in exchange for yellowcake.
  • Tehran has endorsed a proposal to establish a regional nuclear fuel-supply consortium, insisting any arrangement must complement its right to domestic enrichment.
  • IAEA Director General Rafael Mariano Grossi has warned that Iran could resume uranium enrichment in a matter of months and stressed the need to clarify the whereabouts of roughly 400 kg of 60% enriched uranium.
  • US Secretary of State Marco Rubio condemned calls in Iran for the arrest or execution of the IAEA chief and urged Tehran to guarantee the safety and security of its inspectors.
