Iran still needs to convincingly disprove allegations that there was a military dimension to its past nuclear activities, the UN atomic watchdog said on Monday.
"Substantive explanations are required from Iran to support its statements on the alleged studies and on other information witha possible military dimension," the International Atomic Energy Agency said in its latest report on Tehran's disputed nuclear drive.
The IAEA "is continuing to assess the information and explanations provided by Iran," it said.
"However, at this stage, Iran has not provided the agency with all the information, access to documents and access to individuals necessary to support Iran's statements," said the confidential new report, a copy of which was seen by AFP.
"The agency is of the view that Iran may have additional information, in particular on high explosives testing and missile-related activities, which could shed more light on the nature of these alleged studies and which Iran should share with agency."
