Iran says allegations that it is pursuing a clandestine and non-peaceful nuclear program have been proved to be baseless.
The Iranian envoy to the International Atomic Energy Agency, Ali Asghar Soltanieh, spoke Friday at the end of a two-day meeting of the IAEA's 35-member board in Vienna.
Those at the meeting examined an IAEA report that credits Iran with progress in revealing details about its nuclear program, but also says Tehran continues to defy U.N. demands to stop enriching uranium. That process can be used to make nuclear weapons.
IAEA chief Mohamed ElBaradei told the board Thursday that, despite greater cooperation from Tehran in key areas, the agency is not able to confirm that Iran's nuclear work is entirely peaceful.
In Iran, officials Friday warned against efforts by the U.N. Security Council to pursue further sanctions against their country.
The IAEA report may determine whether the Security Council decides to impose a third set of sanctions on Iran, which Western nations accuse of seeking to covertly develop nuclear weapons. Iran says its nuclear program is peaceful.
