BRUSSELS — Representatives of six world powers urged Iran on Friday to accept a U.N. plan aimed at delaying its ability to build a nuclear weapon, as the head of the U.N. nuclear watchdog agency warned Tehran not to miss the opportunity to resolve the dispute.
A European Union official said there was no mention of imposing sanctions against Iran for its refusal to halt nuclear enrichment activities at the meeting of senior diplomats from the U.N. Security Council’s five permanent members plus Germany.
A statement issued by the diplomats expressed disappointment over Iran’s failure to engage in intensified dialogue since a promising meeting Oct. 1 in Geneva. The West says Iran agreed in principle to export uranium for enrichment during those talks — something Iranian officials have denied.
