IAEA loses track of 900 pounds of potentially enriched uranium after Iranian officials removed it ahead of US military strikes that caused "very serious damage" to nuclear facilities.

Iran's enriched uranium is central to Israeli and U.S. justifications for their attacks. According to the IAEA, Iran has enriched more than 400 kilograms − about 880 pounds − of uranium to 60%, enough to make around nine nuclear weapons if it is further enriched to weapons grade, which is around 90%.
