IAEA

The UN's nuclear watchdog, responsible for verifying Iran's compliance with nuclear non-proliferation commitments. The IAEA's reports on Iranian enrichment levels are the primary evidence base for the nuclear talks.

The International Atomic Energy Agency was established in 1957 as the 'Atoms for Peace' organisation. It has 178 member states and conducts safeguards inspections at nuclear facilities worldwide. Iran has significantly restricted IAEA inspector access since 2021, limiting the agency's ability to verify enrichment activities. IAEA reports showing Iran enriching to 60% purity are central to the 2025 nuclear talks.
