The United Nations atomic watchdog says Iran has exceeded a so-called soft limit on sensitive material that was set under its 2015 nuclear deal with world powers.
In a report released on November 9, the day after Republican candidate Donald Trump won the U.S. presidential election, the International Atomic Energy Agency (IAEA) said Tehran had surpassed the 130-ton threshold for heavy water since the deal came into force in January.
The watchdog said Tehran had stockpiled 130.1 tons of the material, which is used at reactors like Iran’s unfinished facility at Arak.
The last time Iran briefly went over the 130-metric-ton mark, there was no major criticism from the world powers that signed the nuclear deal with Tehran.
But there are questions about whether there would be the same reaction from the incoming administration of Trump -- who has called the accord a "bad deal" and vowed to renegotiate the agreement.
The IAEA said Iran told the agency it is preparing to transfer 5 tons of heavy water out of the country in the coming days as provided for in the nuclear agreement.
