The United States on Thursday blacklisted Hamza, a son of late al-Qaeda leader Osama bin Laden saying he is "actively engaged" in terrorism.
Bin Laden, who is in his late 20s, has called for terror acts in western capitals and threatened to take revenge against the U.S. for his father’s killing, the U.S. State Department said in a statement.
He was declared member of the group by senior leader Ayman al-Zawahiri in 2015.
In a separate statement, the U.S. State Department also announced designation of Ibrahim al-Banna as a Specially Designated Global Terrorist.
The man was described as a senior member of al-Qaida in the Arabian Peninsula (AQAP) leadership who served as the group’s security chief and provided military and security guidance to the leadership.
He has described the 9/11 attack as "virtuous" and threatened to target Americans both domestically and elsewhere. He is also subject to a U.S. reward of up to $5 million.
The sanction means that they any property owned the two men in U.S. may be frozen and U.S. citizens are prohibited from engaging in any transactions with them.
