(KCEN) -- Protesters gathered outside the United Nations to protest Iranian President Mahmoud Ahmadinejad.
The leader spoke before the UN General Assembly this morning. The U.S. delegation walked out.
This comes as tensions rise over Tehran's nuclear program.
There is also talk of a possible attack on Iran by Israel.
Today Ahmadinejad did not mention his nation's controversial nuclear program.
Instead he accused big powers like the U.S. and Israel of being bullies.
He said, "Continued threat by the uncivilized Zionists to resort to military action against our great nation is a clear example of this bitter reality."
Ahmadinejad's speeches are known for being controversial.
In past years several delegations have walked out when he criticized countries that he said used the Holocaust as an excuse to pay ransom to Zionists.
