Iran said Sunday it was standing by its "right" to enrich uranium on its own soil, just a day before talks with Russia aimed at finding a compromise on the ultra-sensitive nuclear work. The negotiations on Moscow's offer to carry out ultra-sensitive uranium enrichment work on Russian soil are seen as a last chance for Tehran to avoid being hauled before the UN Security Council for possible punitive action. Having already been reported to the Security Council, Iran is also under pressure to provide greater access to International Atomic Energy Agency (IAEA) inspectors and return to a full freeze of enrichment work - which can be extended to weapons making."The Islamic Republic is not being stubborn or adventurist, but it will not accept the suppression of its nuclear fuel activities," said Javad Vaidi, a member of Iran's Supreme National Security Council.
