Ayatollah Ali Khamenei has issued a fatwa saying the production, stockpiling and use of nuclear weapons was forbidden under Islam.[49] The fatwa was cited in an official statement by the Iranian government at an August 2005 meeting of the International Atomic Energy Agency (IAEA) in Vienna.[50]
Iran's nuclear program has been a subject of international debate for decades. The Iranian government claims the purpose of its nuclear development is to produce electricity, while some western countries accuse it of trying to create nuclear weapons.
