The United States Treasury told American banks Wednesday to monitor transactions related to members of ousted Egyptian president Hosni Mubarak's government.
The Treasury said the banks should be looking for financial activities that could involve "misappropriated or diverted state assets."
Egyptian opposition leaders have accused members of Mr. Mubarak's government of sending billions of dollars in assets overseas, and are demanding the money be returned.
Egypt asked the U.S. and European Union earlier this week to freeze the assets of some senior officials. The U.S. and EU did not name those on the list, but said Mr. Mubarak was not included.
Individual requests were also sent to the British, French and German governments.
