Explained: What are the limits to the UN nuclear watchdog's oversight in Iran?

Following Israeli strikes on Iranian nuclear facilities, IAEA inspections have been halted. The IAEA's authority is limited to NPT signatories like Iran, but not Israel. Iran's compliance with the Additional Protocol, granting broader inspection powers, was rolled back after the U.S. withdrew from the 2015 nuclear deal, creating gaps in oversight and raising concerns about undeclared nuclear activities.
