TEHRAN - Iran, Brazil and Turkey signed an agreement on Monday over a nuclear fuel swap based on which Iran would ship 1,200 kg of its low-enriched uranium for 120 kilograms of higher-enriched nuclear fuel to power Tehran’s medical reactor.

The exchange would take place in Turkey under the supervision of the International Atomic Energy Agency and Iran, Foreign Ministry spokesman Ramin Mehmanparast said.
""The swap will take place in Turkey,"" Mehmanparast told reporters, shortly before the agreement was signed by foreign ministers of Iran, Turkey and Brazil in front of reporters.
Turkey and Brazil, both non-permanent members of the UN Security Council, had offered to mediate between Iran and the 5+1 group over the stalled nuclear fuel swap proposal.
Brazilian President Luiz Inacio Lula da Silva and Turkish Prime Minister Tayyip Erdogan discussed the deal with Iranian President Mahmoud Ahmadinejad in Tehran.
The trilateral meeting over nuclear fuel swap was held behind closed doors on the sidelines of the G15 summit in Tehran on Monday.
The Turkish prime minister made a sudden visit to Tehran last night after talks between the foreign ministers of Iran, Turkey and Brazil over nuclear fuel swap proved successful.
The Iranian negotiators in the deal were President Ahmadinejad, Supreme National Security Council secretary Saeed Jalili and Foreign Minister Manouchehr Mottaki.
Negotiations over nuclear swap began in Tehran on Sunday between the foreign ministers of Iran, Turkey and Brazil.
