The U.S. government has frozen any U.S. assets belonging to two Syrian officials it accuses of corruption and involvement in terrorism.
Thursday's move by the Treasury Department targets Syrian Interior Minister Ghazi Kanaan and Rustum Ghazali, who is identified as the chief of Syrian military intelligence for Lebanon.
The department says it has information indicating the two men directed Syria's military and security presence in Lebanon, and contributed to Syria's support for terrorism. It says the officials reportedly also benefited from corrupt business deals in Lebanon.
There has been no comment from the Syrian officials.
The Treasury's move is based on an executive order President Bush signed last year that declared a national emergency with respect to Syria.
The Bush administration has accused Syria of keeping intelligence agents in Lebanon despite international demands for a complete Syrian pullout. Damascus denies the allegation.
