The U.N.'s nuclear agency, the International Atomic Energy Agency (IAEA), is pressing Iran to let inspectors back into its nuclear facilities as soon as possible.
Since June 2025, access has been blocked after military actions by Israel and the US making it tough for the IAEA to keep tabs on what is happening inside.
IAEA warns of Bushehr proliferation risk
With only one inspection allowed at the Bushehr plant since restrictions began, the IAEA says not being able to check Iran's nuclear material is a "serious proliferation concern."
Before these limits, Iran had built up about 440kg of uranium enriched close to weapons-grade, enough for serious global worries.
The standoff even got bumped up to the U.N. Security Council in September over Iran's non-compliance with international rules.
