European powers urged Iran on Tuesday to reverse its move to increase uranium enrichment, as a French envoy arrived in Tehran to boost efforts to save a landmark 2015 nuclear deal.

Iran will boost its uranium enrichment after July 7 to whatever levels it needs beyond the cap set in the landmark 2015 nuclear deal

Iran will resume high level enrichment of uranium if world powers did not keep their promises under a 2015 nuclear agreement, President Hassan Rouhani said on Wednesday, responding to the US withdrawal from the deal a year ago.

Iran discussed its plans for nuclear-powered ships with UN nuclear chief Yukiyo Amano on Sunday, saying it would present details within three months, local media reported.
