The Supreme Leader of Iran, Ayatollah Ali Khamenei, called the U.S. an "atomic criminal" at a Tehran conference on nuclear disarmament.
Ayatolla Khamenei said the U.S. is the world's only atomic criminal in a message that was read by an aide at the conference, the BBC reported.
President Mahmoud Ahmadinejad then called on the International Atomic Energy Agency, a UN division, to suspend the country, the BBC reported.
He told the conference that the use of nuclear weapons is prohibited by Islamic law, the BBC reported.
Ahmadinejad also argued that the U.S. has taken no significant measures to disarm itself of nuclear weapons, despite being against weapons proliferation, the China Post reported.
