Guarding Iran's President Ahmadinejad, the Most Hated Man in New York

A small army of U.S. security forces have been marshaled to protect Iranian President Mahmoud Ahmadinejad during his venom-laced stay in New York where he has threatened the U.S. with a "war without boundaries" and suggested the U.S. may have secretly carried out the 9/11 terror attacks.

Law enforcement sources told ABC News that Ahmadinejad has a security force that dwarfs that ofall the other 140 visiting heads of state who are in New York City this week for the U.N. General Assembly.

"It's second only to a POTUS-sized package," a law enforcement official said, referring to the security acronym for the President of the United States.

Another described the force protecting Ahmadinejad the "classic high threat package."
