Iranian President Mahmoud Ahmadinejad is heading to the UN General Assembly with a message of peace and friendship, an aide said on Monday. 'He will leave Tehran tomorrow (Tuesday) to participate in the UN General Assembly meeting in New York,' said Mohammad Jaffar Mohammad Zadeh, information officer in Ahmadinejad's office. 'His main message is to have peace and friendship with all nations based on justice and mutual respect,' the official IRNA news agency quoted him as saying. Mohammad Zadeh added, however, that he expected the 'Zionist lobby' to try 'to stop Iran's righteous words from being conveyed by its elected president to other nations.' Ahmadinejad's visit to the United Nations comes just days after he sparked an international outcry by renewing his suggestion that the Holocaust was a 'myth'. It also comes just days before Iran is due to hold its first talks with world powers on its nuclear programme since Ahmadinejad's hotly disputed re-election in June.
