The International Atomic Energy Agency says it has "no credible" evidence Iran was working on developing a nuclear explosive device after 2009 and that the UN's nuclear watchdog considered the issue "closed" after it was presented in a report in December 2015.
The 2015 report "stated that the agency had no credible indications of activities in Iran relevant to the development of a nuclear explosive device after 2009. Based on the director-general's report, the board of governors declared that its consideration of this issue was closed," the IAEA said in a statement on Tuesday.
"The agency's overall assessment was that a range of activities relevant to the development of a nuclear explosive device were conducted in Iran prior to the end of 2003 as a coordinated effort, and some activities took place after 2003. The agency also assessed that these activities did not advance beyond feasibility and scientific studies, and the acquisition of certain relevant technical competences and capabilities," it added.
