Washington Sep.20 (dpa) - The United States has initiated the so-called snapback process to restore almost all previously lifted UN sanctions against Iran, US Secretary of State Mike Pompeo said in a statement on Saturday.
"Today, the United States welcomes the return of virtually all previously terminated UN sanctions on the Islamic Republic of Iran, the world's leading state sponsor of terror and anti-Semitism," Pompeo said.
He said the snapback of previously terminated UN sanctions became effective at 8 pm Washington time (0000 GMT).
Iranian Foreign Minister Mohammad Javad Zarif rejected the US move, saying that the snapback mechanism and reimposed sanctions were invalid.
"This step is not supported by the UN Security Council because the US is no longer in the nuclear agreement and accordingly no longer plays a role in UN resolution 2231," Zarif said referring to the resolution in which the UNSC backed the Iran nuclear deal signed in Vienna in 2015.
The move by Washington was merely a "propaganda trick" ahead of the US election, Zarif said on Iranian state television.
Washington's plans to reimpose international sanctions on Iran have been met with overwhelming opposition from other countries.
Other members of the UN Security Council (UNSC), including key US allies who are part of the 2015 Iran nuclear deal, have rejected Washington's move and have vowed to ignore it.
Under the nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), Tehran limited its nuclear activities in return for sanctions relief.
"Sanctions are being re-imposed on Iran pursuant to the snapback process under UN Security Council resolution (UNSCR) 2231. On August 20, the United States notified the President of the Security Council of Iran's significant non-performance of its JCPOA commitments," Pompeo said in the Saturday statement.
"Virtually all @UN sanctions have returned on Iran, the leading state sponsor of terrorism and anti-Semitism," Pompeo added on Twitter. "This includes a permanent extension of the arms embargo. This is great news for peace in the region!"
He later added that Washington would soon "announce a range of additional measures to strengthen enforcement of @UN sanctions on Iran."
"Our maximum pressure campaign on the Iranian regime will continue until it stops spreading chaos, violence, and bloodshed," he said.
US special representative for Iran and Venezuela Elliott Abrams had already signalled Washington's determination reimpose sanction on Tehran earlier this week.
The US launched a formal bid in August to revive the UN sanctions under the "snapback" mechanism included in the Iran deal. Those sanctions include the indefinite extension of an arms embargo that would otherwise expire in October.
But few countries believe Washington's move is legal, as US President Donald Trump unilaterally exited the JCPOA in 2018.
Washington said it would provide more information this weekend and next week on how the US intended to enforce the global sanctions.
"In the coming days, the United States will announce a range of additional measures to strengthen implementation of UN sanctions and hold violators accountable," Pompeo said Saturday's statement.
"Our maximum pressure campaign on the Iranian regime will continue until Iran reaches a comprehensive agreement with us to rein in its proliferation threats and stops spreading chaos, violence, and bloodshed," Pompeo asserted.
Trump is likely to address Iran in his speech next week to the UN General Assembly's largely online meeting of world leaders.
The stand-off between the US and other member states over the issue threatens a diplomatic crisis at the world body.
