The quarterly report issued today by the International Atomic Energy Agency is significant considering US President Donald Trump's criticism of the 2015 Iran nuclear deal.
Trump last month refused to certify that Iran was in compliance with the agreement. He said Iran had committed several earlier violations and is receiving disproportionate relief from international sanctions.
He then gave Congress 60 days to review whether the US should re-impose sanctions on Iran or otherwise amend the conditions for participating in the treaty.
