The British government issued a stark warning to Tehran on Wednesday as a senior American envoy began nuclear negotiations in Switzerland. In a statement from the Foreign Office, the UK demanded that Iran halt its enrichment of uranium to near-weapons grade and return to compliance with the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action. The warning comes amid heightened tensions between the West and Iran, with the US envoy, a special representative for Iran under the Trump administration, meeting with Iranian officials in Geneva.
