UN Secretary-General Ban Ki-Moon condemned Iranian President Mahmoud Ahmadinejad's remarks during his address to the General Assembly:
"I strongly condemn the comments made by a leader of a delegation that called into question the cause of the 9/11 terrorist attacks on US soil," Ban said.
US President Barack Obama accused Ahmadinejad of making "offensive" and "hateful" comments when he said most of the world thinks the United States was behind the attacks in order to benefit Israel.
"It was offensive," Obama said. "It was hateful. Particularly for him to make the statement here in Manhatten, just a little north of Ground Zero, where families lost their loved ones, people of all faiths, all ethnicities who see this as the seminal tragedy of this generation, for him to make a statement like that was inexcusable."
