Iran shipped 25,000lb (11,000kg) of low-enriched uranium to Russia, marking a step towards fulfilling its commitments under a historic nuclear deal struck in July. The move is aimed at reducing Iran's ability to make nuclear weapons — something Tehran has long maintained it has no interest in.
US Secretary of State John Kerry, an instrumental force behind the deal, made the announcement on 28 December, saying: "I am pleased to report that we have seen important indications of significant progress towards Iran completing its key nuclear commitments under the deal. This removal of all this enriched material out of Iran is a significant step toward Iran meeting its commitment to have no more than 300 kilograms of low-enriched uranium by implementation day."
