Iran demanded on Tuesday that the U.N. Security Council respond firmly to what it described as Israel''s "unlawful and insolent threats" to launch an attack on Iran''s nuclear facilities.

Israeli officials, including Prime Minister Benjamin Netanyahu and President Shimon Peres, have suggested the Jewish state could use military force to prevent Tehran from developing nuclear weapons, as the West suspects it is doing.

Iran insists it is only interested in building reactors that peacefully generate electricity. Iranian President Mahmoud Ahmadinejad, who has said Israel should be "wiped off the map," has vowed to continue his country''s nuclear program.

Iran''s U.N. ambassador, in a letter to Mexican U.N. Ambassador Claude Heller, said Israel was violating the U.N. charter and urged the international body to respond clearly and resolutely. Mexico holds the rotating presidency of the Security Council.

"These outrageous threats of resorting to criminal and terrorist acts against a sovereign country and a member of the United Nations not only display the aggressive and warmongering nature of the Zionist regime, but also constitute blatant violations of international law," Iranian Ambassador Mohammad Khazaee wrote.
