These designations play a critical role in our fight against terrorism and are an effective means of curtailing support for terrorist activities and pressuring groups to get out of the terrorism business. The consequences of these designations include a prohibition against U.S. persons providing material support or resources to, or engaging in other transactions with KH, and the freezing of all property and interests in property of the organization that are in the United States, or come within the United States, or the control of U.S. persons.
