Iran has less than 24 hours to sign a nuclear swap deal brokered by Turkey and Brazil.
If Iran signs the deal , US plans for a new round of sanctions against Tehran at the UN Security Council could suffer a setback. Iran must write and deliver a letter to the International Atomic Energy Agency (IAEA) to kick start the fuel swap agreement reached on Monday, Aljazeera says.
The statement from Mikhail Margelov, the head of the Federation Council's Foreign Affairs Committee, comes after some diplomats had said that the sanctions under discussion would prevent Russia from delivering S-300 surface-to-air missiles to Iran under an existing contract.
Israel and the United States have asked Russia not to fulfill its contract to deliver the S-300 missile systems to Iran, though diplomats say Moscow is keen to keep the order as a bargaining chip with Tehran, Reuters informs.
Russian officials have repeatedly declared that Israeli aviation poses a threat to the Russian military in Syria.
