U.N. Powers Support New Sanctions Against Iran

The United States has introduced a resolution backed by all veto-wielding members of the U.N. Security Council that would impose new sanctions against Iran.

U.S. Ambassador Susan Rice circulated the resolution to the 10 nonpermanent council members Tuesday, a day after Tehran sought to stave off sanctions through a deal to swap nuclear materials.

Rice said the resolution would give "greater teeth" to existing sanctions and add "strong" new measures to intensify pressure on the Iranian government to resolve concerns that its nuclear program is peaceful and not aimed at producing nuclear weapons.

The draft resolution would target a range of activities related to Iran's nuclear program including the country's powerful Revolutionary Guard, a U.S. official said.
