UN 'believes Iran worked on developing nuclear weapons'
A UN atomic agency has said it believes that Iran worked in the past on nuclear weapons but its activities did not go past planning and basic component experiments.
The assessment was contained in an International Atomic Energy Agency (IAEA) report, ending nearly a decade of attempts to investigate the allegations.
The evaluation said the most "coordinated" work on developing such arms was done before 2003, with some activities continuing up to 2009.
The agency's probe was based on intelligence provided by the United States, Israel and other Iranian adversaries and on the IAEA's own research and interviews.
The confidential report released by the IAEA on Wednesday and obtained by reporters is significant in wrapping up the probe and in preparing the ground for the lifting of sanctions on Tehran.
