U.S. Secretary of State Condoleezza Rice says Iran has so far shown no interest in a proposed European deal over its nuclear program.

Ms. Rice says Iran has given no indication that it will accept the offer of trade benefits in exchange for an end to the Tehran government's nuclear ambitions.

She added that the world is coming to a united position that Iran must not be able to produce a nuclear weapon.  She spoke in Washington ahead of talks with President Bush.

Earlier Thursday, White House spokesman Scott McClellan said Mr. Bush is looking at how the United States can best support the European effort and make sure it gets Iran to abandon its nuclear ambition.

The United States says Iran is secretly trying to develop a nuclear weapon, a charge Iran denies.
