The UN's nuclear watchdog chief, Rafael Grossi, says Iran's cooperation with inspectors is insufficient, despite inspectors' return after a June war. While access to crucial nuclear facilities is improving, many issues remain unresolved. European leaders are considering reimposing sanctions due to Iran's non-compliance with the 2015 nuclear deal, which includes resuming negotiations with the US, granting inspectors full access, and accounting for highly enriched uranium. Grossi, under police protection due to threats, is working to secure full access for inspectors to all Iranian sites. A recent meeting between European and Iranian officials ended without a resolution.
