The UK, France and Germany said on Tuesday that they had “grave concern” about Iran’s decision to announce that it would produce uranium metal for reactor fuel, enriched to up to 20 per cent purity.
"Iran has no credible civilian need for uranium metal R&D and production, which are a key step in the development of a nuclear weapon," the three countries said in a joint statement issued by Britain's foreign ministry.
"We strongly urge Iran to halt all activities in violation of the JCPOA, without delay and to return to the negotiations in Vienna with a view to bringing them to a swift conclusion," the three countries added.
