US moves to clamp down on three Iranian companies

The Bush administration moved Friday to clamp down financially on three Iranian companies suspected of having connections with Teheran's nuclear program. It marked the government's latest move to put the financial squeeze on Iran, which the United States accuses of fostering terrorism and whose nuclear ambitions have drawn international rebuke. The action also comes days after President George W. Bush said he has no doubt the Iranian government is providing armor-piercing weapons to kill American troops in Iraq. The Treasury Department's action is against Kalaye Electric Co. and Kavoshyar Co., both based in Teheran, as well as Pioneer Energy Industries Co. in Isfahan.
