(CNN) -- The United States has announced new sanctions against Iran targeted at the country's nuclear and missile programs -- identifying more than twenty companies and several individuals allegedly involved with those programs.
The U.S. Treasury Department says the measures begin to implement the recent U.N. Security Council Resolution 1929 and highlight "Iran's use of its financial sector, shipping industry and Islamic Revolutionary Guards Corps to carry out and mask its proliferation activities".
Announcing the measures at the White House, Treasury Secretary Tim Geithner said they "are designed to deter other governments and foreign financial institutions from dealing with these entities and thereby supporting Iran's illicit activities".
"In the coming weeks, we will continue to increase the financial pressure on Iran," he said.
