US Treasury clamps down on Iran's nuclear program

The Bush administration moved Friday to clamp down financially on four Iranian companies suspected of connections to Teheran's nuclear program. The Treasury Department's action is against Pars Tarash, Farayand Technique, Fajr Industries Group and Mizan Machine Manufacturing Group. The action means that any bank accounts or other financial assets belonging to these three companies found in the United States must be frozen. Americans also are prohibited from doing business with them.
