The United Kingdom, France and Germany - the E3 group of European powers - expressed concern on Wednesday over Iran's latest moves to enrich uranium up to 60% purity.
"The governments of France, Germany and the United Kingdom (the E3) note with grave concern the announcement by Iran that it will start uranium enrichment up to 60% using advanced centrifuges as Iran communicated to the IAEA on 13 April," they said in a joint statement.
"This is a serious development since the production of highly enriched uranium constitutes an important step in the production of a nuclear weapon. Iran has no credible civilian need for enrichment at this level," they added.
