TEHRAN, Iran (CNN) - Iranian President Mahmoud Ahmadinejad on Monday ruled out nuclear negotiations with other nations, saying, "Iran's nuclear issue is over, in our opinion."
At a news conference in Tehran, the hardline president also said that if re-elected he again will call for a debate with President Obama.
Ahmadinejad previously urged a debate with President Bush and offered to debate both Obama and Republican presidential candidate Sen. John McCain during last year's U.S. presidential campaign.
The Iranian presidential election is June 12.
"I will extend that invitation one more time, so that there and then at the United Nations headquarters, President Obama sits there at the table and discusses world issues management and the way toward peace," Ahmadinejad said, according to a live translation of his remarks.
