Hamza bin Laden, a son of Osama bin Laden, has been officially designated a global terrorist by the United States.
Hamza, who is now in his late 20s, was named an official member of al-Qaeda in 2015 and is seen as a possible successor to his father.
Since then, he has called for attacks against western capitals.
The US State Department said it was notifying the international community that "Hamza bin Laden is actively engaged in terrorism".
The official sanction blocks him from any business dealings with US companies or holding property on US soil.
