Iran has been given a chance to address the UN nuclear watchdog's concerns on uranium particles found at undeclared, old sites and Washington will watch closely, the United States told the watchdog's board on Thursday.
"Iran has now been given another opportunity by the Director-General to offer up the necessary cooperation before this Board next meets," the US statement to the board said, shortly after diplomats said plans for a resolution criticizing Iran had been scrapped.
"The United States, like all Board members, will calibrate our views on the Board's next steps according to whether Iran seizes the opportunity now before it to finally and credibly address the IAEA's concerns," it added.
International Atomic Energy Agency chief Rafael Grossi told a news conference: "I'm ... aiming at having a far more clear understanding of this issue by the summer or before," adding that the first meeting would be in Iran in early April and he hoped to report back to the IAEA board on progress by June.
