The UN nuclear watchdog says Iran has stockpiled at least ten times more uranium than was agreed in the international agreement.
Uranium is used to make nuclear bombs, but Iran has always claimed that its nuclear program is for peaceful purposes.
The International Atomic Energy Agency (IAEA) says Iran’s uranium reserves now stand at 2,105 kg.
The agency made the claim after inspecting one of the two suspected Iranian nuclear sites. They say they will visit the second field later this month.
Since last year, Iran has deliberately and publicly backtracked on its nuclear deal with the six world powers.
In 2015, the agreement was signed by Iran, China, France, Germany, Russia, the United Kingdom and the United States. The United States later withdrew from the deal after Donald Trump came to power.
