VIENNA: The United States, Britain, France and Germany have submitted a motion to the UN atomic energy watchdog to censure Iran over its lack of cooperation with the agency, two diplomats said Tuesday.

“The text was submitted overnight” from Monday to Tuesday, a European diplomat told AFP. A second diplomat confirmed the news.

The resolution urging Iran to cooperate fully with the International Atomic Energy Agency (IAEA) marks the first time since June 2020 when a similar motion censuring Iran was adopted.

It is a sign of growing Western impatience after talks to revive the 2015 landmark nuclear accord with Iran stalled in March.

The vote is likely to happen on Thursday during the week-long meeting of the IAEA’s 35-member Board of Governors, one of the diplomats said.

In a report late last month, the IAEA said it still had questions that were “not clarified” regarding traces of enriched uranium previously found at three sites, which Iran had not declared as having hosted nuclear activities.

IAEA head Rafael Grossi told reporters on Monday after opening the board meeting that he hoped “to solve these things once and for all”.

The negotiations to revive the accord started in April 2021 with the aim of bringing the United States back into the deal, lifting sanctions and getting Iran to scale back its stepped-up nuclear programme.
