Iran has taken a "significant step" towards meeting its nuclear commitments, by sending a large quantity of uranium abroad, according to US Secretary of State John Kerry.
"I am pleased to report that we have seen important indications of significant progress towards Iran completing its key nuclear commitments under the deal," he said, speaking after Monday's shipment of low-enriched uranium to Russia, which means the amount of time it would take Iran to produce enough fuel for a bomb has now tripled.
Under July's agreement, signed with six international world powers, the International Atomic Energy Agency will decide when Tehran has complied with its obligations, after which, the US and other countries will begin to dismantle their programme of economic sanctions against Iran.
