The governments of the UK, Germany and France have expressed ‘grave concern’ over Iran’s move to boost uranium enrichment to 60% in response to what Tehran says was an attack by Israel against its key nuclear facility at Natanz. The three European countries say the announcement is ‘particularly regrettable’ at a time when talks in Vienna have resumed, including the United States, to revive the 2015 nuclear deal. They also said this was showing Iran to be on the path to a nuclear weapon, adding, ‘Iran has no credible civilian need for enrichment at this level’.
