Some Iranian nuclear facilities will have to be shut for good in the next phase, US Secretary of State John Kerry says after a deal is reached to temporarily halt its nuclear programme, dpa reported.
"That will require dismantling certain things, that will require stopping certain things," he says of a future comprehensive deal that the US, Britain, China, France, Russia and Germany are seeking.
Such steps would provide the ultimate proof that Iran does not aim to build nuclear weapons, Kerry says in Geneva.
