Iran Blocks UN Access to Bombed Nuclear Sites, Raises Enrichment Concerns

• Iran has denied IAEA inspectors access to nuclear sites struck during a June conflict involving Israel and the US.
• The UN watchdog cannot confirm if Tehran halted uranium enrichment or determine current enriched uranium quantities.
• Inspectors haven't visited Iran's four declared enrichment plants since the attacks, disrupting "continuity of knowledge."
• Lack of access to Isfahan Fuel Enrichment Plant for over eight months prevents assessment of nuclear material or operations.
• Concerns rise over Iran's 400+ kg stockpile of 60-percent enriched uranium, last seen by inspectors on June 10.
