UN: Iran worked on developing nuclear weapons
Iran took limited steps towards developing a nuclear bomb in the past, the UN's nuclear watchdog has said.
But the report from the IAEA said the efforts did not go beyond planning and testing of basic components.
Iran's Deputy Foreign Minister Abbas Araqchi said the findings confirmed that Tehran's nuclear programme was peaceful, BBC reports.
The report was a condition of this year's landmark deal between Iran and six world powers.
The July agreement involves the lifting of sanctions in return for Iran curbing sensitive nuclear activities.
In its report, the IAEA said most of the "co-ordinated" work by Iran took place before 2003, with some activities continuing up to 2009.
But it added "these activities did not advance beyond feasibility and scientific studies, and the acquisition of certain relevant technical competences and capabilities".
