President Obama speaking ahead of a summit in Seoul, South Korea, has told leaders that the US has no hostile intention towards them and will pursue the diplomatic route but they must give up their nuclear weapons.

Soundbite President Obama:

"There is time to solve this diplomatically, but time is short. Iran's leaders must understand that there is no escaping the choice before it. Iran must act with the seriousness and sense of urgency that this moment demands. Iran must meet its obligations."

Tehran has said, its nuclear programme is purely peaceful, but Israel and Western nations believe it is moving towards a nuclear bomb that could change the regional balance of power.
