Iran has struck a nuclear deal with Turkey and Brazil, designed to allay international concerns over its atomic ambitions and avert fresh sanctions.
Tehran says it will exchange 1,200 kilos of its low-enriched uranium for higher-enriched nuclear fuel from abroad, for a medical research reactor.
President Mahmoud Ahmadinejad, who rejects Western claims that Iran wants to develop nuclear bombs, has agreed the swap can happen in Turkey, possibly within a month.
It follows a visit to Tehran by Turkish Prime Minister Recep Tayyip Erdogan and Brazil’s President Lula da Silva. Their mediation was seen as a last chance to avoid a new round of UN sanctions against the Islamic Republic.
Ahmadinejad has urged fresh talks with world powers on Iran’s nuclear programme. But scepticism is likely as the country has made a similar pledge before, only to back out of a deal.
