Iran Supreme Leader rules out atomic bomb

Iran will never develop a nuclear bomb but will not give up its pursuit of peaceful nuclear energy, says Supreme Leader Ayatollah Ali Khamenei.

"Our motto is nuclear energy for all and nuclear weapons for none," Khamenei told 120 representatives at the Non-Aligned Movement summit in Tehran.

The West suspects Iran's nuclear programme is focused on developing a nuclear bomb, an accusation dismissed by Tehran.

Late on Wednesday, visiting United Nations Secretary General Ban Ki-moon urged Iran to take concrete steps to prove the country's nuclear programme was peaceful.

Khamenei's speech the following day also took aim at the U.N. Security Council, describing it as an illogical, unjust and defunct relic of the past that the United States uses to, quote "impose their bullying manner on the world."
