Teheran has proposed building joint light-water nuclear power plants with neighboring Arab countries, Iran's official news agency, IRNA, said Sunday. The report quoted the head of the Atomic Energy Organization of Iran, Gholam Reza Aghazadeh. He said Iran was ready to offer a proposal to Arab countries if they are interested. Iran's Arab neighbors have been suspicious of the Islamic Republic's controversial nuclear program, and several Arab countries have announced plans to develop their own nuclear programs. The US and some of its allies claim Iran is secretly trying to develop nuclear weapons - a charge Teheran denies. Iran is building its first nuclear power plant with Russia's help. It is slated to open in 2009.
