Ahmadinejad: Iran doesn't need the bomb

Iranian President Mahmoud Ahmadinejad insisted Thursday that Tehran doesn't need atomic weapons and he is "at a loss" about what more he can do to prove that. Ahmadinejad said his country has not hidden anything and was working within the framework of the Nuclear Non-Proliferation Treaty.

"The bottom line is we do not need a bomb," he said at a news conference on the sidelines of the U.N. General Assembly.
