U.N. Nuke Chief Heads to Iran

To meet with top officials.

On Sunday, International Atomic Energy Agency chief Yukiya Amano will land in Tehran to sign a deal allowing the United Nation's nuclear agency to bring back its investigation into whether Iran was developing nuclear arms. A six-country meeting has been planned with Iran for later next week as well. Iran had blocked the inquiry's access since shortly after it launched in 2007, but now may be hoping their cooperation will stop the U.N. Security Council's demand that they end higher-level enrichment of uranium. Diplomats have said they might allow Tehran’s right to make low-enriched uranium for energy if it stops producing uranium enriched to 20 percent, material which could be used for warheads.
