The United Nations’ nuclear watchdog confirmed Monday that Iran has installed advanced centrifuges and is moving toward enriching uranium levels — another violation of the 2015 nuclear deal brokered by world powers.

The International Atomic Energy Agency verified the existence of the centrifuges and said they had been “prepared for testing” but had not yet been made operational.

Iran last week announced its intention to use the centrifuges and has already surpassed the levels set by the accord on enriching uranium in an effort to get the countries still participating to help ease economic sanctions imposed by the US after the US withdrew from the deal last May.

Britain, France, Germany, China, Russia and the European Union have been trying to salvage the Obama administration-era agreement that limits Iran to operating 5,060 older-model IR-1 centrifuges.

But the IAEA said its inspectors saw 30 advanced IR-6 models, as well as a number of IR-4 and IR-5 models.

The deal provided economic incentives to Tehran for assurances that its nuclear power program would only be used for peaceful purposes.

“The agency continues to verify and monitor Iran’s nuclear-related commitments under the JCPOA,” IAEA acting director general Cornel Feruta said in a statement, referring to the accord’s formal title, the Joint Comprehensive Plan of Action. “Evaluations regarding the absence of undeclared nuclear material and activities in Iran continue.”
