France, Britain and Germany expressed concern after Iran planned to install more uranium enrichment centrifuges, urging Tehran to stop action.

"The plan to deploy more modern centrifuges at Iran's Natanz nuclear plant goes against the nuclear deal and is very worrying. If Tehran seriously wants to pursue diplomatic measures, it cannot be implemented.

The announcement comes after Reuters published a confidential report of the International Atomic Energy Organization (IAEA), which stated that Tehran plans to install three more advanced centrifuges IR-2M at

The Joint Comprehensive Plan of Action (JCPOA) nuclear agreement signed by Iran with six powers in 2015 only allows the country to use the first generation IR-1 centrifuge, which has uranium enrichment rates

The three European powers emphasized legislation that would allow the Iranian government to stop UN inspections and accelerate uranium enrichment beyond the JCPOA limit, nor was it consistent with the agreement, as well as non-universal commitments.

"That move could undermine a joint effort to protect the JCPOA, as well as threaten to hinder the administration's plan to resume diplomatic measures. The return to the JCPOA will benefit Iran,"

Iran has repeatedly broken commitments in the JCPOA in response to President Donald Trump's withdrawal from the U.S. deal in 2018 and re-imposing economic sanctions.

Iran earlier this year announced it would not comply with JCPOA nuclear limits such as the development of a uranium enrichment centrifuge, the level of enrichment, the amount of allowed uranium reserves or research and development activities.
