US government places sanctions against Syrian chemists after attack

The U.S. government put 271 Syrian chemists and other officials on its financial blacklist April 24, punishing them for their presumed role in the deadly chemical weapons attack on a rebel-held town in early April.

In one of its largest-ever sanctions announcements, the Treasury Department took aim at the Syrian Scientific Studies and Research Center (SSRC), which it said was responsible for developing the alleged sarin gas weapon used in the April 4 attack.

The attack left 87 dead, including many children, in the town of Khan Sheikhun, provoking outrage in the West, which accused Syrian President Bashar al-Assad of being responsible.

The sanctions will freeze all assets in the United States belonging to the 271 individuals on the blacklist, and block any American person or business from dealing with them.

According to the Nuclear Threat Initiative, a Washington-based think tank, the SSRC is Syria’s leading scientific research center, with close links to the country’s military.
