Iranian official media reports that a measure to halt collaboration with the International Atomic Energy Agency (IAEA) has been adopted by the Iranian Parliament.
The bill also forbids IAEA inspectors from entering Iranian nuclear sites unless their security is ensured. It was passed with 222 votes in favor, none against, and one abstention.
After recent regional escalations, the action indicates rising tensions between Iran and international nuclear watchdogs.
Tehran is said to be responding to growing threats to its nuclear infrastructure with the law.
