President Hassan Rouhani has said that on 7 July his country would exceed the 3.67% uranium enrichment limit set by the 2015 nuclear deal by ‘as much as necessary, as much as we need’. Iran will reverse this action if the other parties to the deal - Britain, China, France, Germany and Russia - abide by their commitments. The agreed enrichment limit is sufficient for power generation, but far below the 90% level needed to manufacture nuclear weapons. Rouhani also said Iran would restart construction of a heavy water reactor, and bring it to the condition that ‘according to you, is dangerous and can produce plutonium’. Iran has often threatened such action unless it gets some relief from the sanctions imposed on the country. The five other signatories of the deal are struggling to keep it afloat after US president Donald Trump walked out of it last year.
