The report also spelled out that Iran's cooperation with IAEA continues to be "less than satisfactory" in "a number of respects".

Iran's Foreign Ministry and the Iranian nuclear agency called the report "politically motivated" in a joint statement. They said Tehran will take "appropriate measures" in response to any effort to take action against the country at the Board of Governors meeting, state media reported. 

Iran’s Foreign Ministry also accused Israel of providing unreliable and false information to the IAEA for use in its report.

Tehran says it wants to master nuclear technology for peaceful purposes and has long denied accusations by Western powers that it is seeking to develop nuclear weapons.
