A top adviser to Barack Obama says the president will not meet with Iranian President Mahmoud Ahmadinejad (ah-muh-DEE'-neh-zhahd) at the United Nations next week.

U.S. ambassador to the U.N. Susan Rice says she doesn't expect the two to have "direct engagement."

Obama will be in New York from Monday to Thursday for the gathering of the 192-member U.N. General Assembly.

Rice spoke on Friday, the same day Ahmadinejad lashed out at Israel and the West and again questioned whether the Holocaust happened.

Rice called those comments "hateful." White House spokesman Robert Gibbs told reporters: "Obviously we condemn what he said."

The U.S. accuses Iran of running an illicit nuclear weapons program. Iran denies that.
