The International Atomic Energy Agency (IAEA), the United Nations' nuclear watchdog, has formally declared Iran in breach of its nuclear non-proliferation guidelines for the first time in 20 years.
In a resolution supported by 19 of the IAEA's 35 board members, including the United States, United Kingdom, France, and Germany, the agency criticized Iran's refusal to explain undeclared nuclear material and its stockpile of uranium enriched near weapons-grade levels, UN News reported.
Iran rejected the resolution as politically driven, announcing plans to construct a new enrichment facility. It argues that its nuclear program is harmless.
The move follows a 2018 decision by US President Donald Trump to withdraw from the 2015 nuclear deal, after which Iran began scaling back its compliance, according to UN News.
