The United States is urging the U.N. Security Council to redouble efforts to implement sanctions against Iran.

U.S. Ambassador Susan Rice told the council Wednesday that fully implementing sanctions "will show Iran there is a price to pay for its deception."

She said stepped up implementation can also slow down Iran's nuclear program and buy time to resolve the Iranian nuclear crisis through diplomatic means.

Iran is under U.N. Security Council sanctions because of concerns it is seeking to develop nuclear weapons.

A recent report by the U.N. nuclear agency concluded that some alleged clandestine work by Iran could not be used for any other purpose than making nuclear arms. Iran insists its peaceful nuclear program is aimed solely at producing energy.
