(RT.com) -- The UN Atomic Agency unveiled its report that claims Iran has worked on developing a nuclear weapon design. This follows the aggressive rhetoric of politicians, calling on Israeli hotheads to curb their angry approach.

"The report of the International Atomic Energy Agency is unbalanced, unprofessional and politically motivated," Iran's envoy to the IAEA, Ali Asghar Soltanieh, was quoted as saying by Reuters. The report does not contain any new issue, added Soltanieh, who talked to journalist after the report was revealed.

The Iranian media say the report is based on documents dating back to 2004, and may have been cooked up by Western special services to back the case against Tehran.

Hours before the report release, President Mahmoud Ahmadinejad condemned the paper calling the head of the International Atomic Energy Agency, Yukiya Amano, a pawn for US interests. On Tuesday, President Ahmadinejad stated  in an interview that his country does not need a nuclear bomb to oppose the US and will rather rely on “mind, logic and culture”.

"If America wants to confront the Iranian nation, it will certainly regret the Iranian nation's response," Ahmadinejad was quoted as saying by the IRNA news agency.

Washington preferred to withhold any comment until the State Department finishes studying the 25-page long report by the Atomic agency. The reaction might not emerge till the next IAEA session scheduled for November 18.

Earlier on Tuesday Russian president Dmitry Medvedev issued a grave warning about the consequences of militaristic rhetoric in the Middle East.

“We understand how ramped up the passions in the Middle East are, the situation some countries face and the fact that the peace process is stalled. If a militaristic tide is stirred in these circumstances, if threats are voiced, it may provoke very serious consequences,” Dmitry Medvedev said during a joint press conference with his German counterpart, Angela Merkel.

He added that the parties involved should “take a breath and calm down,” because otherwise the dispute could lead to a major war and a catastrophe for the whole region.

France also voiced strong words against an attack on Iran on Tuesday. The country’s foreign minister, Alain Juppé, said Paris may support a new round of sanctions against Tehran if necessary, but called for parties to refrain from any military action, since it would cause irrevocable damage.

The calls for restraint came in the wake of statements by Israeli Defense Minister Ehud Barak, who said that a strike is more likely than diplomacy and may be used unless “crippling sanctions” against Iran are issued.
