The head of the UN nuclear watchdog agency IAEA today said that Iran is still not cooperating with the IAEA to show that its nuclear programme is peaceful. International Atomic Energy Agency chief Yukiya Amano also requested Iran to take steps towards the full implementation of its Safeguards Agreement and its other obligations. Iran denies that it is trying to build a nuclear bomb, and insists that its uranium enrichment programme is to make medical isotopes. Amano told the Board of Governors of the International Atomic Energy Agency that full implementation by Iran of its binding obligations is needed to establish international confidence in the exclusively peaceful nature of Iran's nuclear programme. In June last year, the UN Security Council passed a fourth round of sanctions against Iran for running its nuclear programme without transparency and violating previous Security Council resolutions along with the Nuclear Non-Proliferation Treaty. The resolution, however, did not pass unanimously. There were 12 votes in favour but both Turkey and Brazil voted against while Lebanon abstained.
