The Department of State has designated Hamza bin Laden as a Specially Designated Global Terrorist (SDGT) under section 1(b) of Executive Order (E.O.) 13224, which imposes sanctions on foreign persons determined to have committed, or pose a serious risk of committing, acts of terrorism that threaten the security of U.S. nationals or the national security, foreign policy, or economy of the United States. As a result of this designation, all property subject to U.S. jurisdiction in which Hamza bin Laden has any interest is blocked and U.S. persons are generally prohibited from engaging in any transactions with him.
On August 14, 2015 Hamza bin Laden, son of Usama bin Laden, was officially announced by al-Qa'ida senior leader Ayman al-Zawahiri as an official member of the group. In this 2015 audio message from al-Zawahiri, bin Laden called for acts of terrorism in western capitals. On July 9, 2016, al-Qa'ida issued another audio message from Hamza bin Laden threatening revenge against the United States and warned Americans they would be targeted in the United States and abroad. Specifically, in 2015, bin Laden called for lone offender attacks against U.S., French, and Israeli interests in Washington, D.C.; Paris, France; and Tel Aviv, Israel. Additionally, in 2016, bin Laden called on Saudi Arabian-based tribes to unite with al-Qa'ida's affiliate in Yemen to wage war against the Kingdom of Saudi Arabia.
The imposition of sanctions by the United States against terrorists is a powerful tool. Today's action notifies the U.S. public and the international community that Hamza bin Laden is actively engaged in terrorism. Designations of terrorist individuals and groups expose and isolate organizations and individuals, and result in denial of access to the U.S. financial system. Moreover, designations can assist or complement the law enforcement actions of other U.S. agencies and other governments.
