The interview from the Iranian capital will be broadcast Monday on the network's evening news program, which starts at 6:30 pm (2230 GMT), with NBC anchor Brian Williams sitting down with Ahmadinejad, NBC announced.

On Wednesday Ahmadinejad vowed that Iran would not yield to the two-week deadline set by six world powers to respond to their latest offer to move ahead in the crisis over Tehran's uranium enrichment program, which the powers believe is aimed at developing nuclear weapons.

The six -- the United States, Britain, France, Russia, China, and Germany -- have offered to start pre-negotiations during which Tehran would add no more uranium-enriching centrifuges and in return face no further sanctions -- the so-called "freeze-for-freeze" approach.
