Iran's supreme leader says he sees no benefit to negotiations with the United States on his country's nuclear program.

Ayatollah Ali Khamenei added Iran will not negotiate its right to use nuclear technology with anyone. But he says Iran is willing to discuss international supervision of its program if other countries accept Iran's right to a nuclear program.

The United States has offered to join European talks with Iran if it first agrees to suspend uranium enrichment.

On Monday, Iranian nuclear negotiator Ali Larijani said Iran is seriously considering a package of international incentives aimed at convincing Iran to abandon enrichment. He said Iran will respond as soon as possible to the offer from the five permanent members of the United Nations Security Council and Germany.

The United States and its European allies accuse Iran of trying to develop nuclear weapons. Tehran denies the allegation.
