Venezuela and Cuba Thursday rejected taking Iran nuclear dossier to the UN Security Council at the executive body of the International Atomic Energy Agency (IAEA) in Vienna.

"We are going to vote no, and we expect Cuba does it too," Venezuelan ambassador Gustavo Márquez Marín told reporters, as quoted by AFP.

Venezuela was the only country that voted to reject a resolution taking Iran nuke dossier to the UN Security Council at the end of September last year.

World powers, including Russia and China, have agreed to take the Iranian issue to the Security Council, according to several diplomatic sources.

Meanwhile, in a communiqué, Cuba, a new member of IAEA board of governors, said it "firmly opposes to the use of this sovereign decision as a new excuse to condemn that country (Iran)."
