The United States on Tuesday urged Iran to live up to its obligations to abandon its alleged ambitions for nuclear weapons.

"Iran has certain international obligations that they have committed to. We want to see them live up to those obligations... That means coming clean and fully cooperating with the International Atomic Energy Agency and fully complying with those international obligations.

"Ultimately, we want to see the permanent end to Iran's reprocessing and enrichment activities. That will be a key to make sure that they are not developing nuclear weapons," White House spokesman Scott McClellan said.

"What we want to do is make sure that Iran does not acquire a nuclear weapon," McClellan noted.

The United States accuses Iran of using atomic energy as a cover for weapons development. Iran denies US allegations, and says its nuclear program is solely geared to generating electricity.
