Obama tells Iran it must stand up on nuke program

UNITED NATIONS — President Barack Obama called for Iran to demonstrate a "clear and credible commitment" to a peaceful nuclear program while addressing the United Nations General Assembly in New York on Thursday.
At the same time, the US president told fellow world leaders that the "door remains open to diplomacy should Iran choose to walk through it." But Obama also noted that he made the same overture — in the same forum — a year ago, and tensions continue.
President Mahmoud Ahmadinejad, in an interview Sunday with The Associated Press, said "the future belongs to Iran," and challenged the United States to accept that Tehran has a major role in world affairs.
