France, Britain and Germany expressed frustration on Saturday at Iran's demand - in talks to revive its 2015 nuclear deal - for the UN nuclear watchdog to end an investigation into uranium particles found at three sites, adding that it is putting the negotiations at risk.This month, Iran sent its latest response to the European Union's proposed text for the deal under which Tehran had curbed its nuclear program in exchange for easing economic sanctions from the United States, the European Union and the United Nations.Diplomats argue that Iran's response to the EU coordinator was a setback, with the country seeking to link the resumption of the deal with the termination of the International Atomic Energy Agency's (IAEA) investigation into traces of uranium."This latest demand raises serious doubts about Iran's intentions and commitment to a successful outcome," the three countries, known as the E3, said in a statement.Then-President Donald Trump left the deal in 2018 and reimposed U.S. sanctions, prompting Iran to violate the deal's nuclear restrictions, as well as reviving fears in the U.S., Arab countries and Israel that the country may be seeking of an atomic bomb.Iran denies having nuclear ambitions.Follow Money Times on Facebook!Like our Facebook page and connect with Money Times journalists and readers.Our team brings you the most important discussions of the day and you participate in conversations about the news and analysis of everything that happens in Brazil and in the world.Follow the Money Times Facebook page now!Last updated by André Luiz - 09/10/2022 - 13:13
