WASHINGTON (AP) - The State Department is belittling Iran's offer to let some countries - but not the U.S. - visit its nuclear facilities, calling the offer a "magical mystery tour."

Department spokesman P.J. Crowley said Tuesday that the offer is no substitute for Iran fully cooperating with the International Atomic Energy Agency to prove that its nuclear program is strictly for peaceful purposes and not to build a bomb.

Reporters asked Crowley how the U.S. felt about Iran's decision not to include the U.S. in the countries invited to tour a nuclear enrichment plant at Natanz and other facilities. Crowley responded sarcastically, saying, "We're just crushed."

While the State Department spokesman did not urge others to decline the invitation, he did say that there is no reason for any country to attend.
