Britain says Iran's move on nuclear deal is a threat to national security

• Dominic Raab said on Tuesday that Iran's decision to take a new step to reduce commitments to a landmark 2015 nuclear deal.
• Iran's latest actions clearly contravene the deal and pose a risk to our national security.
• Iran said on Monday it had launched a new batch of advanced centrifuges to accelerate uranium.

Iran said on Monday it had launched a new batch of advanced centrifuges to accelerate uranium enrichment, following the withdrawal from the nuclear pact by the United States.

"Iran's latest actions clearly contravene the deal and pose a risk to our national security," Raab said.

"We want to find a way forward through constructive international dialogue but Iran needs to stand by the commitments it made and urgently return to full compliance."
