Iran: initial nuclear deal agreed
Abbas Araghchi made the comments to the official IRNA news agency. He said world powers and the Iranian government should respond within two days about whether they accept the terms.
An official from a member country of the United Nations nuclear agency who is closely following the talks said a preliminary agreement was reached tonight.
While not a final deal, it maps out a first-step agreement for six months as diplomats negotiate a final deal. A November deal calls for capping Iran's uranium enrichment programme in return for an easing of some international sanctions.
