Iran will revise the nuclear fuel swap deal if it has to face further sanctions, Interfax news agency quoted Iran's ambassador to Moscow as saying on Tuesday.
Iran signed a nuclear fuel swap agreement with Turkey and Brazil in May, Xinhua reported.
According to the agreement, the Tehran government has agreed to a draft proposal whereby Iran will send some 1,200 kg of its 3.5 percent enriched uranium over to Turkey in exchange for a total of 120 kg 20-percent uranium needed for a medical research reactor.
Iran has officially handed to the IAEA chief a letter on the deal.
