The Atomic Energy Organization of Iran (AEOI) made the announcement on Wednesday.

The AEOI said the UN atomic body has not appreciated Iran's good-will gesture and has instead viewed Tehran’s voluntary move as part of its undertakings.

The AEOI noted that for these reasons, it orders the Online Enrichment Monitor and the flow meter to be taken offline.

It however noted that 80 percent of the IAEA’s surveillance cameras are within Iran’s undertakings under the safeguards agreement and will remain in place to continue operation.

The decision has been taken amid a meeting of the IAEA’s Board of Governors. The event is reportedly set to adopt an anti-Iran resolution, drafted by Britain, France, Germany, and the US, to allegedly accuse the Islamic Republic of withholding cooperation with the agency.

The expected adoption of the resolution also comes following a trip by IAEA Chief Rafael Grossi to the Israeli-occupied territories.

Iran has previously cautioned the IAEA against allowing the Israeli regime—which is leading a constant bid aimed at incriminating Iran’s nuclear work—against allowing Tel Aviv to influence the agency’s independent mandate and decision-making.

The Israeli regime continues to be the sole possessor of nuclear arms in the Middle East region, with a stockpile of hundreds of atomic warheads. Due to the cover provided by the US and Europeans, however, the regime has always refused to open up its nuclear sites to IAEA inspectors and also refused to join the Nuclear Non-Proliferation Treaty (NPT).

Iranian Foreign Minister Hossein Amir Abdollahian warned on Sunday that those who support or sponsor adoption of a resolution against Iran at the IAEA will account for its consequences.

“Those who push for anti-Iran resolution at IAEA will be responsible for all the consequences,” Amir Abdollahian wrote on his twitter page.

“We welcome a good, strong and lasting agreement,” he added.

“It's within reach if US/E3 (Washington and the European trio) are realistic,” Amir Abdollahian said.

Iran has also repeatedly cautioned in the past that adoption of an anti-Iranian resolution was counterproductive to ongoing talks aimed at reviving a 2015 nuclear deal between Iran and world powers.
