Speaking at a press conference today President Mahmoud Ahmadinejad invited representatives of the P5+1 to travel to Tehran and “pick up” the Iranian government’s latest proposal. But, he cautioned, discussions over the nuclear program are “finished.” More from Thomas Erdbrink of the Washington Post Foreign Service:

The statement came as the head of the United Nations’ nuclear watchdog announced that his agency was locked in a “stalemate” with Iran. The Obama administration has offered to open talks with Iran on nuclear and other issues, and Mohamed ElBaradei of the International Atomic Energy Agency said he has urged Iran “to respond positively to the recent U.S. initiative.”
“We made the proposal ready this week. I think we sent out the invitations to the representatives of the countries to come and receive it,” Ahmadinejad said. The semiofficial Iranian Students News Agency said Iran was likely to unveil the package by the end of this week.
Although Ahmadinejad said Iran was not willing to discuss limits on its nuclear program, he said it was prepared for talks on the peaceful use of nuclear energy worldwide and “an effective management to prevent proliferation of nuclear weapons and promote global disarmament.”
