Rice warns of more U.S. sanctions on Iran

PALO ALTO, May 22 (Reuters) - The United States will "aggressively" impose more sanctions on Iran as long as it refuses to give up sensitive nuclear work and uses the world's financial system for "terrorism," U.S. Secretary of State Condoleezza Rice said on Thursday.

The Bush administration assessed "practically every day" whether to slap more sanctions on Iran, Rice said on a trip to California with British Foreign Secretary David Miliband.

"We will continue to designate entities as we find them trying to use the international financial system for ill-gotten gains and yes we are going to continue to do it and we will continue to do it aggressively," she said.

"Iran should not be in a position of using the banking system to pass profits made from terrorism or proliferation," she added.

Iran has been subjected to three rounds of U.N. Security Council sanctions over its nuclear program and the United States in October designated the elite Qods military force of Iran's Revolutionary Guard a supporter of terrorism.
