United Nations ? U.N. ambassadors from six world powers agreed in principle Wednesday on a proposed new package of sanctions against Iran and were expected to introduce a resolution to the Security Council today if their governments approve it, the U.S. ambassador said.

The package still needs to be considered by the 10 nonpermanent members of the U.N. Security Council that haven’t been part of the negotiations. However, an agreement by the five veto-wielding permanent members of the council and Germany would be a strong signal that they want to send a united message to Iran to suspend uranium enrichment.

“We have an agreement in principle based on some additional changes that were introduced and presented today by some delegations,” acting U.S. Ambassador Alejandro Wolff said.

He said the new elements needed to be approved by government officials in each of the five countries that hold permanent council seats – the U.S., Russia, China, France and Britain.
