Katya Adler talks to Dr Ali Asghar Soltanieh, Iran's ambassador to the UN's nuclear watchdog, the IAEA.Iran's nuclear power programme has been a source of international tension for the past decade. At no point has it been able to shrug off the suspicion that its pursuit of nuclear energy is also an effort to make nuclear weapons. Iran insists it has no such ambitions but many of the world's major powers remain unconvinced and Israel is warning it will attack. The international community is seeking assurances from Iran at a fresh round of talks in Moscow later this month. Katya Adler asks Dr Ali Asghar Soltanieh what guarantees Iran will give that its nuclear ambitions are entirely peaceful.(Image: Iranian Ambassador to the International Atomic Energy Agency (IAEA) Ali Asghar Soltanieh.
