A couple living in Massachusetts exported electronics to aid Syrian dictator Bashar Assad’s chemical weapons program, the Treasury Department said Wednesday in a statement announcing new sanctions.

“Syria’s horrific use of chemical weapons, including attacks against innocent women and children, remains deeply embedded in our minds,” said Sigal Mandelker, Treasury’s under secretary for terrorism and financial intelligence. “Today, we are continuing our campaign to stop the Assad regime’s ruthless attacks by targeting the procurement networks that have supported its chemical weapons program.”
