The Treasury department announced sanctions against 29 Syrian government officials and six companies. The new penalties come as several top regime officials were killed July 18 in a bombing attack.

The move freezes the officials’ assets in U.S. jurisdictions and bars Americans from doing business with them. Sanctions are already in place on Syrian security officials, and this step extends the sanctions to virtually the entire government.

“Today's actions reflect the unwavering commitment of the United States to pressure the Assad regime to end the carnage and relinquish power,” Treasury Undersecretary for Terrorism and Financial Intelligence David Cohen said in a statement. “As long as Assad stays in power, the bloodshed and instability in Syria will only mount, and we will continue working with our partners in the international community to ensure that the inevitable political transition occurs as rapidly as possible.”
