President Mahmoud Ahmadinejad left Tehran yesterday/ on Saturday for New York and the UN General Assembly, where he will deliver his final speech to the world gathering. His speech this year is keenly awaited in the face of sharp differences with the UN Security Council over Iran's controversial nuclear program, and Israeli threats to launch pre-emptive strikes on Iranian nuclear facilities. Before leaving Tehran, the president told reporters he would be stressing issues raised in an Iran-hosted summit of non-aligned nations, particularly on UN reform and solving regional issues, including Syria, putting an end to the violence there. It will be Ahmadinejad's last address to the UN's 193 member states. Next year, he is to step down after serving his second and final term as president.
